You know, you may actually be onto something. If they proposed that debate, that would be definite put-up or shut-up situation to Obama's worshippers/Sarah's detractors. Obama'd be damned if he accepted and damned if he rejected.
Its not just that. People would immediately begin to ask: why do they want Palin debating Obama and not Biden? Obviously, the knee jerk response from the MSM would be: Its because they’re afraid of Joe Biden!
Well that may or may not be. But what does it say for Barack Obama, their presidential nominee, if the GOP thinks they stand a better chance against him in a debate than the VP Biden?
It makes Obama look like the weakling on the ticket.
