It's time to ask a question, the answer to which we do not know: Will former Secretary of State Hillary Clinton's private email server scandal do fatal damage to her campaign?
Over the past few months it's become clearer that the questions surrounding Clinton's emails — and a corresponding flood of negative press that she has been unable to counteract — have done considerable harm, at least in the short term. Her favorability rating has continued to erode. In June, we noted that despite months of questions about her emails — the story broke in early March — Clinton's net favorability had only gone from 48%-46% favorable to 46%-48% unfavorable, according to HuffPost Pollster's average. Since then, her unfavorability has only inched up to 49%, but her favorability has dropped to about 41%.
The fact that her unfavorability number hasn't grown much while her favorability number has clearly dropped suggests that some Democrats and Democratic-leaning independents are not willing to say they like their party's frontrunner right now, but they also aren't willing to say they dislike her. These are the voters that Clinton, as the nominee, would probably be able to bring back into the fold. Polarization raises the floor for candidates of both parties, even ones who are damaged.
So perhaps the damage is only temporary.
However, it's possible to imagine that the email scandal could get so bad that it would drive Clinton from the race. It's certainly not something we'd predict right now, but we also can't rule it out. Not when the FBI is sniffing around and Clinton felt compelled, after months of stalling, to turn over her private server, and when there are indications that those tens of thousands of emails she deleted might be retrievable on a backup server.
Clinton could be brought down by facts about the emails we don't know. Her secretive behavior has reinforced preexisting suspicions, as she's reminded voters of the consistent scent of scandal that has hung around the Clintons ever since they arrived on the national scene. Like so many other Clinton scandals, this one might roll off their backs. Or it might be the one that sticks.
If Clinton does leave the race, then Katie, bar the door: Every Democratic governor and senator will look in the mirror and see a future president.
However: If she remains in the contest, which is still highly probable, we continue to believe Clinton is a very formidable favorite for her party's nomination.
Our argument for Clinton's primary strength is largely unchanged from last month, and we won't reiterate those points here in detail. The case for Clinton, in short, is this: Party leaders still overwhelmingly support Clinton over any other contenders; the impressive crowds that Clinton's chief rival, Sen. Bernie Sanders (VT), has been attracting have no predictive value; Clinton is widely supported by Democratic women and minorities, both of whom have a dominant say in the primary process; and the primary calendar suggests looking beyond the very white, unrepresentative opening contests of Iowa and New Hampshire to the more diverse contests that follow, where Clinton should be stronger than Sanders.
But what if Clinton's perceived weakness draws other candidates into the race even as she remains? This brings us to the rumor of the moment: a potential run by Vice President Joe Biden.
Dartmouth College's Brendan Nyhan, a shrewd analyst who has contributed to the Crystal Ball, recently argued that Biden already is running. Not because he has announced a decision, but because the growing media buzz around his potential candidacy is a way for Biden and his allies to "test the waters." If donors, elected Democratic officials, and others are receptive to his candidacy, Biden might actually run. If they are not, he won't.
In effect, Biden is doing what 2012 Republican nominee Mitt Romney did at the start of 2015, when he semi-publicly considered a candidacy. The reaction among GOP elites to a third Romney run was mixed at best, so Romney passed. If Biden does run, it will tell us that Democratic elites are less sold on Clinton than her long list of endorsements from sitting party officials would suggest, and that the email scandal and her declining favorability have done her harm.
But just because a Biden run would add to Clinton's mounting list of woes doesn't automatically mean Biden is a truly serious threat to win the nomination.
As a candidate, Biden would find himself in an unenviable situation. So long as Clinton remains in the race, Biden would have to contend with her daunting funding, organization, and popularity in the party (which remains quite strong). And if Clinton is not in the race, it is unlikely Biden would have to contend only with Sanders, former Gov. Martin O'Malley (MD), and the other existing candidates: As noted above, a Clinton-less field could entice several others to launch a late entrance. It's unclear whether Biden would be the favorite in a reshuffled Democratic presidential scrum.
That's because, for a sitting vice president, Biden is unintimidating.
Throughout the entire presidential cycle — going all the way back to 2013 — Clinton has led every single national poll of Democrats, and even in her weakened state her level of support in every poll is near or over 50%. Biden, on the other hand, has never reached even 20% in any national primary poll included in RealClearPolitics' list, and his average in the most recent surveys is 12%. That strikes us as a fairly weak number for a sitting vice president who did not, unlike former Vice President Dick Cheney, frequently and loudly insist he was not considering a run for president. There just has not been much grassroots support for Biden.
Now, there's an important caveat here. If Biden actually announces his run, his poll numbers will assuredly improve. But by how much? It's hard to say, but it doesn't seem likely that he would jump ahead of Clinton in the polls. It's also not impossible that a Biden run would hurt Sanders more than Clinton. Although Clinton and Biden are ideologically closer to each other than either is to the socialist senator, Sanders is benefitting somewhat from the perception that he is the leading alternative to Clinton among the currently announced candidates.
Biden's two previous presidential runs in 1988 and 2008 were busts. He was forced from the former race long before voting started in part because of accusations that he plagiarized from the stump speech of British Labour Party leader Neil Kinnock. More recently, in 2008, Biden's candidacy was almost inert, barely registering in Iowa before he dropped out.
Biden's public persona as a scrappy underdog from Scranton also feels increasingly out of step with the diverse Democratic Party, particularly because of the things Biden has often said — "You cannot go to a 7-11 or a Dunkin' Donuts unless you have a slight Indian accent. I'm not joking." — and done — getting much too close to Secretary of Defense Ash Carter's wife (pawing her, in fact, to her obvious discomfort) during Carter's swearing-in earlier this year. These incidents are problematic when running for the nomination of a party increasingly reliant on women and minorities.
This gets at Biden's perception problem: To many, it's impossible to separate Biden the vice president from Biden the caricature. One of the most popular running gags on The Onion, the satirical news site, is poking fun at "Diamond Joe" Biden (example headlines: "Shirtless Biden Washes Trans Am In White House Driveway" and "Biden To Cool His Heels in Mexico For A While"). His frequent gaffes make him the subject of ridicule, and conservatives have criticized press coverage of Biden for years, saying that the vice president gets away with behavior that would imperil Republicans.
