Why don’t you look at your screen name and then tell me why you would think anyone in the GOP except the very liberal elite would vote for the baby killer supporter Obama. It is one thing to ask why the Hillary supporters detest Obama but it is another to ask why Republicans don’t do the same against McCain. McCain/Palin are firmly pro-life.
I will answer the question on the Hillary supporters but frankly your question makes me suspect.
It is easy — Hillary lost the election because of ACORN voter fraud in the caucus system. They have a series of videos detailing the fraud in TX and IN. Then we have Howard Dean on FL and MI giving equal votes when Obama was not on the ballot in MI. Then at the Convention they stopped voting in the middle of the roll call. Also Obama/Dean/Pelosi/Reid twisted arms of Super Delegates. They saw how condescending Obama treated Hillary and when he passed over for the VP, they went into action. They were on board before then.
Most of the PUMAs and other groups are not full fledged socialist which is what the Dem Party has become.

TX is split but IN is a closed primary, straight up, no caucus chaser. And Hillary didn't lose IN.
