Republicans need to win only 4 of the 16 competitive Senate races in order to keep control of the Senate, but if you’re a conservative, particularly if you’re a pro-lifer, you need a lot more than 50 GOP senators.

Here’s why: Trump may not be able to appoint a pro-life judge to the Supreme Court with a slim majority, thanks to pro-choice GOP senators such as Lisa Murkowski, R-Alaska, and Susan Collins, R-Maine. Sure, Collins voted for Brett Kavanaugh’s confirmation, but Kavanaugh was hand-picked by Justice Anthony Kennedy, who helped save most of Roe v. Wade.
