A brewing Republican versus Republican fight over whether to use a government funding measure to choke off Obamacare is splitting the party ahead of this fall's budget battles.
A growing number of Republicans are rejecting calls from leading conservatives, including Sens. Marco Rubio, Ted Cruz and Rand Paul, to defund the president's health care law in the resolution to keep the government running past Sept. 30. The rift exposes an emerging divide over how the GOP can best achieve its No. 1 goal — to repeal Obamacare — while highlighting the spreading fears that Republicans would lose a public relations war if the dispute leads to a government shutdown in the fall.
