Key Democrats to watch in Gorsuch showdownCheck The Source Here:https://goo.gl/EuEJ3fBe a Proud Patriot, Wear Your America T-Shrits: https://goo.gl/XgtvW8Several key Democrats are keeping their votes to themselves days before a showdown over Supreme Court nominee Neil Gorsuch's confirmation.Gorsuch needs 60 votes to end a filibuster backed by most Democrats, meaning the GOP needs to pick off eight members of the minority. If Democrats block Gorsuch, Republicans promise to go "nuclear," ordering a vote to change the Senate's rules to allow his nomination to go forward on a majority vote. Some voices on the left and the right appear to be hoping for such an outcome, though a group of centrist Democrats is trying to ward off that showdown. They are warning fellow Democratic senators that their party should not filibuster Gorsuch, warning it could lead to eliminating the filibuster for legislation.Two centrist Democrats, Sens. Joe Manchin (W.Va.) and Heidi Heitkamp (N.D.), announced late Thursday that they would vote for Gorsuch. Both face reelection next year in states that Trump carried by big margins in 2016.Republicans control 52 seats and now need six more Democrats or Independents to support advancing his nomination to a final up-or-down vote to get over the 60-vote bar and avoid a showdown over the rules.Three Republican senators told The Hill Thursday that their caucus is unified on the question of changing the rules if Democrats block Gorsuch with a filibuster.They claim it would be tougher to change the rules when the next court vacancy occurs, because that seat could swing the ideological balance of the court and reverse the right to an abortion established by the 1973 Supreme Court decision in Roe v. Wade.Triggering a rules change to confirm Gorsuch is a slam dunk, they add, because the future makeup of the Supreme Court was a major issue for voters in 2016, the nominee is a well-qualified 10-year veteran of the 10th Circuit Court of appeals and the vacant seat belonged to the late conservative Justice Antonin Scalia.While the debate over Gorsuch has ratcheted up this week, several Democrats haven't gone public with their positions. Here's a look at some of the key Democrats.Sen. Dianne Feinstein (D-Calif.)Feinstein is the ranking Democrat on the Senate Judiciary Committee and has stressed that her concerns over how Gorsuch would rule on abortion rights during confirmation hearings earlier this month.Out of respect for the institution, she wants the committee to complete its process of reviewing and voting on his nomination before stating her position.“This process is important to me, and I want it to conclude and the discussion is not a long time away. It’s next week. So you’re going to find out,” she told reporters.
