There is, however, one pick who checks off every box for Hillary Clinton, who matches her strengths without hurting the ticket in other ways, who gives her the opportunity to groom a successor, who delivers broad support both from the Democratic base and independents, and who won’t fold in a debate with the Republican VP candidate. Hillary Clinton should pick Joe Biden as her running mate, for a single term as vice president.
Biden has the chops, the name ID, and a reservoir of goodwill among Democrats, Obama coalition voters, and the working-class white voters that Donald Trump is attracting, plus the toughness to stand shoulder-to-shoulder with Hillary, and toe-to-toe with the Republicans. Unlike a lesser-known pick, there will be no surprises with Joe Biden, and his free-wheeling style is a perfect counter-punch to the Trump phenomenon that would also afford Hillary the luxury of remaining a few feet above the fray.
A third Biden term would also give the deep Democratic bench time to come into focus, and perhaps shore up thin credentials like Castro’s.
Hillary Clinton’s greatest asset in this general election will be her toughness, and that’s an asset she can’t afford to have diluted by a weak running mate. Joe Biden is the rare pick that can match her toughness without overshadowing her, and whose unique resumé makes him something of a Rosetta Stone for huge groups of voters.
Then, after he’s served his four years, and helped shepherd the confirmation of Chief Justice Barack Obama, Biden can make way for the next VP pick when Hillary runs for her second term.
I certainly wouldn't mind Biden, but the major, major problem with Biden is that it puts two white Democrats on the same ticket in the post-Obama era. That's something that might be an issue. Biden making way for Castro in 2020 would go a long way, but I'm not sure Biden's going to be a ton of help in getting the votes that Hillary would have trouble getting in 2016.
Yes, it would be a major reinforcement of keeping President Obama's policies, absolutely. But that's what Hillary should be running on anyway.
I respect Tommy's argument and it does make sense on paper, Biden as the foil to Trump, and let's face it, it's not like Republicans have been making good Veep choices lately. Biden for a single term might not be a terrible idea, but I don't know if he really wants it.
