"Embroiled in a tough reelection fight, Sen. John McCain (R-AZ) worries presumptive Republican nominee Donald Trump would overstep the chief executives’s legal bounds if elected president. Along similar lines, Rep. Tom Cole (R-OK) is concerned Trump’s proposed Muslim ban violates the constitution. And Gov. Nikki Haley (R-SC) warns that Trump’s divisive rhetoric could lead to more violent incidents like the racially motivated mass shooting at a Charleston church that claimed nine lives. Yet despite those concerns, all three have pledged to support Trump, raising the question of just what it would take for them to disavow a candidate who has done anything but moderate his positions since locking up the Republican nomination."
