Methodist are historically amillennialial. But as it is with most Methodist beliefs, you'll find a wide range of views on the subject of eschatology. I've been reading a little here and there about the subject for years and tend to lean towards an Ante-Nicene type historic premillenialism.
I grew up Southern Baptist which is predominately dispensationalist. The teaching never made sense to me as a child. I'd hear dramatic Sunday School lessons about Roman persecution of the early church, then hear a few weeks later about the horrors of the tribulation that we were going to magically get to escape via the pre-mil Rapture. Never did add up to me.
Bush grew up Episcopalian; they teach the amillennial view as do many Methodist, so I'd guess that's his stance.
You're not going to find many UMC Pat Robertson fans!
