Problem with your theory is that liberal republicans advance the democrat agenda. Like John Cornyn providing that critical cloture vote so Harry Reid could remove the debt limit.
Best to rid one party of it's liberals, and it's easier to do that to the republicans.

The ballot is set for Nov. 4, 2014. The choice of a different candidate passed on
May 20, 2014 with their primary.
One of the following will represent Oregon in the Senate come Jan. 2015:
Merkley - Democrat
Wehby - Republican
Montchalin - Libertarian
Sannes - Independent
King - Unaffiliated
I’ll take a GOP in order to maybe get control of the Senate and be able to set some
of the agenda. It’s damned certain with the democrats in charge they will set the agenda.
