As the most unpopular Senate Democrat up for re-election, Claire McCaskill needs all the help she can get. Chuck Schumer and his Super PAC, Senate Majority PAC, have come to her defense as noted recently by Roll Call:
“The candidate in need of the most help, judging by the PAC’s giving, is Claire McCaskill of Missouri. She has a mostly liberal voting record despite a constituency that supported President Donald Trump in 2016 by 18.5 percentage points. She faces a tough vote this fall on a new Supreme Court nominee.”
Missourians know McCaskill has more in common with liberals like Schumer than she does with those she represents, which is why he is spending millions to try to keep her in Washington.
