Never take advice from the opposition. The national party has been punished because they haven't been fiscally conservative and have come across as intrusive puritans. There are many Republicans/faux conservatives, even here on FR, who support totalitarian police state power, intrusion into the lives of adults for things that only affect an individual and are anti-science. The general public notices this and for obvious reasons want no part of it.
The American people are fiscally conservative, social libertarian, detest abortion, and not anti-intellectual. The present form of the GOP is not this way.
There, I edited for completeness.
