Conservatives take aim at McConnell's fundraising strength in GOP civil war

The civil war within the Senate GOP conference is getting heated as conservatives step up calls to curb the power of the next Senate Republican leader, while current Republican Leader Mitch McConnell’s (Ky.) mainstream and moderate allies warn the changes could make the upper chamber as chaotic as the House.

Conservatives led by Sens. Mike Lee (R-Utah), Ron Johnson (R-Wis.), Rick Scott (R-Fla.) and Ted Cruz (R-Texas) have called for putting a term limit on the next leader and demanded more control of the Senate floor.
