Fifty-three percent of Democrats don't have enough of an opinion about VPstakes winner Joe Biden to have an opinion about the long-serving U.S. senator, according to one poll. Another poll of Americans has 23 percent who say they've never heard of him and another 28 percent don't have an opinion.
Obviously anyone who has watched politics and policy closely know who Biden is, and to be honest it's not even Labor Day yet, so a huge chunk of Americans have other things to worry about -- like the cost of gas or kids starting school. Joe Who? is a perfectly reasonable response by many.
McCain's up next. Mitt Who?
