Relationship Between Sens. McConnell and McCain Set To Become Awkward in the Coming Months

McConnell is restricted by an upcoming primary battle while McCain takes up role negotiating with Democrats

The relationship between Senate Republican Leader Mitch McConnell (Ky.) and Sen. John McCain (R-Ariz.) is going to be awkward in the coming months.

McConnell finds himself increasingly constrained by both his new primary challenger and McCain's expanded deal-making role with Democrats. 

Republican senators told The Hill on Wednesday that McConnell is in danger of looking weak if McCain again seizes the leadership reins as he did to broker a deal to avert the "nuclear option" on President Obama's executive nominees.
