I've never heard "Vote Republican" but that's probably because its illegal to do so (Even though that's the most moronic thing ever, free speech applies to religious leaders too.) That said, I have heard pastors give advice on how to vote. They didn't tell us who to vote for, but they did give Godly principles to vote based on. I actually heard 2 services shortly before election day, in different churches. One of them was much more open about the issue, the other one is my regular church. Our pastor just basically outlined Godly principles for voting, but the other church basically implied we should not vote democrat. I actually, in hindsight, prefer the way the other church did it, but not because of what they said (I didn't actually agree with the way they portrayed every issue) but because they weren't afraid to give an honest, frank opinion instead of dancing around the issue.
