Liberal groups are looking to use that energy to ramp up pressure against Republican senators to break with McConnell, particularly those who are in competitive races or who have said in the past that they would not confirm a nominee before Inauguration Day. Most see GOP Sens. Lisa Murkowski of Alaska, Cory Gardner of Colorado and Mitt Romney of Utah as being the most promising after Sen. Susan Collins of Maine, who said Saturday that the appointment to the Supreme Court should be made by the president who is elected on Nov. 3.

Demand Justice is launching a $10 million ad campaign in an effort to stop Republicans from filling Ginsburg’s seat before the presidential inauguration in January. Women’s March is planning big protests. Indivisible has mobilized its members to call Republicans’ offices in the Senate and demand that they “refuse to hold any hearings or confirm any new justices until the next term begins,” according to a prepared script.

The group also said it already has campaign infrastructure in place seeking to oust 12 Senate Republicans, which was originally created in response to the Senate’s impeachment acquittal of Trump, that it plans to utilize in the weeks ahead.
