What if Obama had been white?

In looking at a recent post by Laura Clawson wherein she avers correctly that

Republicans [maintained] they were going to block everything President Obama tried to gain partisan points and make it easier to defeat him in 2012

it occurred to me that this set of circumstances was made so much easier by the fact that Obama is an African-American. That is, the hoi polloi willing to listen to the nonsense Repubicans have been spouting for the past number of years certainly are more willing to back any anti-Obama policy because they can't get past the fact of Obama's heritage. Even when it comes to such an advantageous perk as health care, the Republican lackeys can't get past their prejudice. To be sure, there's a reason Repubs have opposed every single beneficial proposal BO has made, but it's clear (to me, at least) how their followers have accepted their foolish and disadvantageous contrariness.
