Biden-pushers, the Obama/Biden admin is also "vulnerable" to allegations in a GE, too.

This idea that Biden should run because "it would be so easy for the GOP to attack Hillary in a GE" is not only indicative of amnesia of the 1990s (none of the witchhunts yielded more than smoke-and-mirrors), but it also erroneously assumes that the GOP wouldn't have any ammo to attack Biden's ethics/morals with.

That's called "wishful thinking." I personally think the attacks on Obama, like with Clintons, are bunk. But saying only Clinton and not Biden is "vulnerable" is hypocrisy, and hypocrisy is hypocrisy, which I will call out. Of course they're not doing it now to Biden: Biden's not running, yet. But if he were to run and get the nomination, do you really think they're gonna say "Joe, I don't agree with him, but he's/his administration was honest?" Joe Biden is the number two in the administration, and there is no reason they wouldn't attack Biden's administration (he is the number 2, he does have ownership, and more than Hillary too). Sure Biden's "honest" and "favorable" ratings are currently high, but the GOP isn't just gonna let that rise/stay if he were to get the nod. Having Romney as the opponent sure helped in 2012, but Obama is much more adept on the stump or debate stage than Biden, as is Hillary.

Its not exactly like Biden is Mr. Smooth-Talker you know, given his history of gaffes. I think it would be worse. Judging from Hillary's endurance in most reputable polls, clearly, Americans mainly tune out to most basely media crap. The GOP will still control the House in 2016 (the election is in Nov, inaug in Jan), so if he were to seek and get the nomination, it would be foolish to think that they would spare him there either if he's the target. And it'll hurt that he'd lack the money/organization to fight it, unlike the Clintons. Biden into 2016 is nothing but a trap.
