A Republican bill to repeal Obamacare is putting several senators who are up for re-election in a difficult bind.
Forced to choose between backing legislation that satisfies the longstanding GOP goal of ending the law and maintaining health care coverage for their constituents, these senators are, so far, going with the former.
The latest lawmaker to make that choice is Sen. John McCain (R-Ariz.), who told reporters at a Christian Science Monitor breakfast on Wednesday that he would back the bill even though it would end the Medicaid expansion in his home state of Arizona.
