The summer has not been kind to Hillary Clinton. The drip-drip-drip of revelations about her possible misuse and mishandling of classified information threatens to become a deluge in the fall. They have taken a serious toll on her reputation — and even more notably, her treatment by liberal media figures who surely would rather she be elected even if the Risen Christ were to be the Republican nominee.

Democrats are worried — so worried five donors who raised millions for President Obama as well as Obama’s chief Florida strategist have both sworn off Hillary and joined an effort to draft Vice President Joe Biden to save the party from an unelectable (or, dare we say it, indicted) nominee.

Should they be worried? Sure. People in politics should always worry, and since she kicked off her presidential campaign by talking about being “dead broke,” Hillary has been a worry-generating machine for any rational non-Pollyanna Democrat who doesn’t live in a Media Matters for America bubble.

But is Joe Biden a serious Plan B? No. There is no Plan B.

First, the case for Democratic panic. We begin with the perception problem. I’m profoundly skeptical about polling results these days, but politics runs on them, and Democrats are looking at polls that suggest Americans as a whole view her as dishonest and untrustworthy — polls in which the numbers are getting worse as the months pass.

More troubling for those who worry about the condition of the Democratic candidate come November 2016, the most recent Quinnipiac poll says one of every five Democrats say she’s dishonest. In theory, that’s bad. Very bad. If she doesn’t repair her reputation with these core voters, Clinton will be in deep trouble when she needs them most.

There are few things that we know can depress turnout and have done so in the past, and one of them is having ill feelings about the candidate running on your party’s ticket.

George W. Bush was hit by a late-breaking story the week before the 2000 election about a drunk-driving arrest and may have lost a few million votes as a result among disappointed evangelicals in the closest presidential race of our lifetime.

t’s possible that without that story, which raised questions about Bush’s essential character, there would have been no Florida battle, no hanging chads and no cloud of illegitimacy hanging over his first term.

Even more worrisome, when it comes to garnering support among the independents she will have to add to her Democratic turnout to get over the 50% hump is the fact that in the same Quinnipiac poll, Americans say the chief qualities they want in the next president are . . . honesty and trustworthiness.

But that doesn’t make Joe Biden the answer, despite The New York Times’ best efforts to put him on the front page. Joe Biden is clearly a decent fellow, and it’s impossible not to feel for him based on the horrendous family tragedies he has suffered, especially this year with the awful death of his son Beau at the age of 46.

But there’s a good reason he didn’t get into the race a year ago, and it’s the same reason Democrats earlier this year were six times as likely to say they wanted her as their nominee rather than Biden.

He is, let’s face it, a pretty silly person. Hillary is many things, but silly she isn’t. The more Biden speaks — and he speaks a lot — the more likely he is to utter something ridiculous. Or grab some unsuspecting supporter for a back rub.

Earlier this year, in just one of a hundred examples of Bidenisms, he said this of the Somalis living in his home state of Delaware in the capital of Dover: “If you come to the train station with me, you’ll notice I have great relationships with them because there’s an awful lot driving cabs and are friends of mine. For real. I’m not being solicitous. I’m being serious.”

What of Democratic flavor-of-the-month Bernie Sanders? Please. When conservatives say Barack Obama is a socialist, liberals scream at us. But Bernie Sanders is a socialist, full stop. And even in 2016 America, that’s a bridge too far for all but a handful of states.

The Great Mentioner will always murmur the names of Elizabeth Warren and Joaquin Castro and even New York’s own Kirsten Gillibrand, but they have major weaknesses and there’s little evidence they have the stuff to go all the way.

Democrats are stuck with Hillary. At least she has the brand name. Given the brilliance of the Democratic vote-generating machine, even a wounded Hillary likely goes into the election with about 48% of the vote in her pocket. Biden and Bernie won’t even get that.

Of course, all of this goes out the window if Hillary is indicted. Then you’ll see a Democratic feeding frenzy that will make the Republican primary season thus far look like a game of tiddlywinks.
