Which religious group has the most control over the GOP?

Evangelicals due their sheer size.

The GOP has a broad range of conservative Christianity, but the number of Mormons/traditional Catholics/conservative mainlines is still quite small compared to the massive number of Baptists, Pentecostals etc.

The idea that a religious group has control over the GOP is farcical. It's the other way around.

Indeed.  The fundies may be pulling the sleigh, but it's big money that is holding the reigns.  Sometimes the churchy people might pull the sleigh in a direction money doesn't want, but money can handle taking a non direct route to their goals.

Isn't religion the biggest cash-cow of all? But really, I think you could be right. There's probably just as much (if not more) politicking in churches as there is preaching on the campaign trail.

Eh, that really depends on the church in question. Some outright refuse to do politics, while other's might was well put an elephant or donkey next to the cross in the interior of the church. However, it is secular big business that has the biggest pull of all on the GOP.
