And he even said so himself.

she’s (Hillary Clinton) easily qualified to be vice president of the United States of America, and quite frankly, it might have been a better pick than me.

Then-Vice-Presidential Candidate Joe Biden
September 10, 2008
Ok, the quote is four years old. I’m rehashing old stuff. I get that. But before we go into total crazy Paul Ryan hysteria because of a budget bill he submitted, let’s keep things in perspective here. On one hand, we have Paul Ryan, the House Budget Committee Chairman who put forward a proposal to cut federal spending and rein in the deficit. On the other hand, we have a sitting Vice-President who continually puts his foot in his mouth.
Now VP Biden is telling us about a President Romney, “They are going to put y’all back in chains.”
Sure, Ryan needs to be publicly vetted, I get that. That’s why people are going over his budget bill with a fine-toothed comb and quite possibly some other spin from time to time. But is it too late to also take a look at what the other VP candidate in the race brings to the table?
Maybe we can get an idea on how these guys think simply by what they say.
Paul Ryan: “If we don’t make tough decisions today our children are going to have to make much, much tougher decisions tomorrow.”
Joe Biden: “When the stock market crashed (in 1929), Franklin D. Roosevelt got on the television and didn’t just talk about the, you know, the princes of greed. He said, ‘Look, here’s what happened.”
…
Paul Ryan: “Look, I am not worried about Washington cutting too much spending too fast. I mean, the kinds of spending cuts we’re talking about just right now are $100 billion out of a $3.7 trillion budget.”
Joe Biden: “Look, John’s last-minute economic plan does nothing to tackle the number-one job facing the middle class, and it happens to be, as Barack says, a three-letter word: jobs. J-O-B-S, jobs.”
…
Paul Ryan: “The debt and the deficit is just getting out of control, and the administration is still pumping through billions upon trillions of new spending. That does not grow the economy.”
Joe Biden: “You cannot go to a 7-11 or a Dunkin’ Donuts unless you have a slight Indian accent…. I’m not joking.”
…
Paul Ryan: “To my great disappointment, it appears that the politics of division are making a big comeback. Many Americans share my disappointment – especially those who were filled with great hope a few years ago, when then-Senator Obama announced his candidacy in Springfield, Illinois.”
Joe Biden: “I mean, you got the first mainstream African-American who is articulate and bright and clean and a nice-looking guy. I mean, that’s a storybook, man.”
And that’s just a few of the many. Like I said, it makes perfect sense to try to get an idea of who Paul Ryan is and what he stands for and what kind of Vice-President he’d make. But at the same time, take a look at the body of work of our current Vice-President. If the decisions of the #2 guy on the ticket are enough to sway your vote, make sure you get an updated view on the current guy.
