Interesting PRRI survey numbers on religious left/religious right

Mainlines as defined in the media can be a pretty broad range. Let's not forget that UMC member George W. Bush could be considered a mainline Protestant.

Perhaps because the UMC is a mainline denomination?  Granted it is probably the least liberal of the mainline churches, but it is still one of them. Indeed, it's the largest of them nationally, tho locally they're about equal with the ELCA.

However, it's clear that Dubya joined the UMC because Laura was already a member.
