Ensign: GOP shouldn’t focus on abortion or gay rights.

With Democrats expanding their control of the Senate to a solid majority, National Republican Senatorial Committee Chairman John Ensign (R-NV) is arguing that Senate Republicans need to “re-establish what the Republican Party is all about.” Calling for a return to a “big tent Republican Party,” Ensign says that issues like abortion and gay rights “should not be at the core of the party“:
