Senate Democrats elevated their attacks against President Donald Trump's Supreme Court nominee Wednesday, portraying him as an ally of the powerful and an enemy of the weak as an explosive showdown loomed on the Senate floor. Republicans defended Judge Neil Gorsuch, accusing Democrats of trying to block him out of frustration over Trump's election victory.

"Democrats would filibuster Ruth Bader Ginsburg if President Donald Trump nominated her," said Majority Leader Mitch McConnell, R-Ky., naming one of the more liberal sitting justices. "There is simply no principled reason to oppose this exceptional, exceptional Supreme Court nominee."

Democrats begged to differ, returning again and again to McConnell's decision last year to deny consideration to then-President Barack Obama's Supreme Court nominee, Judge Merrick Garland, who was ignored for nearly a year by Senate Republicans after the death of Justice Antonin Scalia.

Instead McConnell kept Scalia's seat open, a calculation that is now paying off hugely for Republicans and Trump, who will be able to claim the biggest victory of his presidency to date if Gorsuch is confirmed on Friday as expected.
