What do voters think of Rob Portman? They don't, a poll finds. Some 51% don't have an opinion on the man currently most likely to join Mitt Romney's ticket, the highest "no opinion" figure about pretty much anything in a Washington Post-ABC poll since September. Those who know who the Ohio senator is aren't wild about him: Some 19% have a favorable view of him, compared to 30% with an unfavorable view. (Among Republicans, the breakdown in 21% to 22%.)
As for potential VP Marco Rubio, 39% take no stance on the Florida senator—even though he pops up frequently in the press. Some six in 10 Republicans do have an opinion, however, and 46% of them see him favorably, while 14% aren't such big fans. Jeb Bush is better known, but he once again offered a definitive "no" this week when questioned about the position. But this actually may not matter one bit: a CNN poll found 51% lacked an opinion on Joe Biden when Obama chose him. Besides, VP picks haven't clearly helped a candidate since John F. Kennedy chose Lyndon Johnson, the Post notes.
