How Many Senators Is Mitch McConnell Willing To Sacrifice?:
"This is just one in a string of states in which Republican obstruction is tanking the poll numbers of GOP senators. Incumbents in New Hampshire, Wisconsin and Pennsylvania all find themselves in electoral hot water. Even Arizona’s John McCain is now in a tight reelection contest and Senate Judiciary Committee Chairman Chuck Grassley has seen a 29-point drop in net approval ratings in his home state. This polling collapse is driven by a miscalculation by Senate Majority Leader Mitch McConnell and his leadership team. They believed independent voters would see their blockade of Merrick Garland’s Supreme Court appointment as standard ideological bickering and at worst declare “a pox on both your houses.” In this case, though, voters recognize that the dysfunction they despise in Washington is the fault of Senate Republicans serving the whims of the extremes of their party. With Donald Trump now the likely Republican nominee, senators up for reelection are painted into an even tighter box."
