...and most people haven't heard of him. But those who have heard of him are giving him Dan Quayle-like numbers:

In a nationwide survey taken Sunday, 39% of registered voters call Republican contender Mitt Romney's selection of Ryan "excellent" or "pretty good" while 45% rate it as "only fair" or "poor." Sixteen percent have no opinion.

That's the most tepid reception for a running mate since 1988, when then-vice president George H.W. Bush picked Quayle, an Indiana senator who immediately ran into questions about his draft history during the Vietnam War and whether he was prepared for the presidency.

In comparison, John McCain's surprise choice of then-Alaska governor Sarah Palin four years ago was rated as excellent or good by 46%, fair or poor by 37%.

And this Politico story is packed with unnamed Republican advisers who are very unhappy about the Ryan pick:

“Very not helpful down ballot — very,” said one top Republican consultant.

This is the day the music died,” one Republican operative involved in 2012 races said after the rollout. The operative said that every House candidate now is racing to get ahead of this issue.

Another strategist emailed midway through Romney and Ryan’s first joint event Saturday: “The good news is that this ticket now has a vision. The bad news is that vision is basically just a chart of numbers used to justify policies that are extremely unpopular.”

For the sake of reference, it took a couple weeks after her rollout before Republicans started eating Sarah Palin alive.
