How many different ways can Paul tell us how he really feels about McCain's foreign policy? It doesn't look like Ron Paul is going to endorse McCain anytime soon.

Republican Rep. Ron Paul told the Tribune this morning he will not back Sen. John McCain as his party's nominee unless the Arizona senator "has a lot of change of heart."

I can not support anybody with the foreign policy he advocates, you know, perpetual war. That is just so disturbing to me," Paul said."I think it's un-American, un-Constitutional, immoral, and not Republican."

Since McCain's whole strategy is to be the biggest war hawk on the planet, I doubt he'll have that change of heart. If anything, he'll start talking more about Iran. Howie wondered if Paul would be forced to endorse him a few days ago, but that looks highly doubtful.

Paul may feel a great deal of pressure to back McCain. Many of his libertarian supporters say that will never happen.
