Obama Campaign Confident About Joe Biden

As confident as they've been about economic recovery the last three years, or more confident?

The Obama campaign said Tuesday it is confident Vice President Biden will be an effective foil against GOP vice presidential candidate Rep. Paul Ryan despite his latest gaffe.

Biden on Tuesday made headlines when he told a crowd here that the GOP ticket's policies would put "y'all back in chains." The remark was about Wall Street regulations, but the Romney campaign seized on the imagery of slavery to say Biden and Obama had hit a new low.
