Democrat senators fear Christians, especially Catholics, will let their faith blur their legal judgment.
In 2015, six Catholics were on the U.S. Supreme Court when it legalized so-called same-sex marriage. Justice Anthony Kennedy consistently favored so-called gay rights and upheld abortion in a 1992 case. Fellow Catholic Justice Sonia Sotomayor was appointed by President Obama based on her leftist views.
Catholic senators have a long history of voting anti-Catholic — including Ted Kennedy, John Kerry, Tim Kaine, Joe Biden and Nancy Pelosi, to name a few. Catholic Republican Sen. Susan Collins of Maine says she won't approve any Supreme Court nominee that isn't pro-abortion.
"I would not support a nominee who demonstrated hostility to Roe v. Wade," said Collins.
Fellow Catholic Republican Sen. Lisa Murkowski of Alaska is on the same page.
Recent polls show Catholics typically lean left on moral issues:
Bishops themselves push left by spilling far more ink on social justice issues than in fighting moral issues like abortion or same-sex "marriage."
