That can be a problem with rapturistic theology (I mean overly concentrated on this).
More mainline fundies recognize rapture as an event that is both as unpredictable and inevitable as death. For almost all, death will precede it anyhow. The bible warned about rapturistic escapism as well. Be living just like you would if there wasn’t a rapture, and you’ll do well if you’re in it.
I sure do not expect that I will change their minds... but, I have no problem pointing out to them that IF Jesus sent Cruz to rule the roost, Cruz would be winning every primary. They have been reduced to exposing their 'primary colors' (name of a book) and it is not a pretty sight...
