Tim Grieve over at Salon got his hands on a great poll and mined it for all it's worth. I can't really add much to this:
41: Percentage of Americans who, when asked to name a Republican running for president, couldn't.
Eighty-one percent of Americans polled by the Pew Research Center could name at least one Democrat running for president. And if you need one more sign that the Republicans are just a little obsessed with Hillary Clinton, here you go: When asked to name a Democratic candidate, 78 percent of Republicans named Clinton, but only 57 percent of Republicans could name their own front-runner, Rudy Giuliani.
Overall, 62 percent of Americans could volunteer the name of Barack Obama. Twenty-eight percent remembered that John Edwards is running, but no other Democrat cracked the double-digit barrier.
Asked to name any GOP candidates in the race, 45 percent of Americans named Giuliani; 30 percent said Mitt Romney; 27 percent I.D.'d Fred Thompson; and 24 percent mentioned John McCain. Only eight percent of Americans volunteered the name of Mike Huckabee. Seven percent did the same for Ron Paul.
