Kavanaugh's confirmation fires up progressives ahead of midterms

But Collins’ decision to back Kavanaugh also has helped inspire liberal activists to donate their time as well as their campaign cash.

MobilizeAmerica, an online platform that connects volunteers to liberal groups and candidates, saw a surge in activity as Collins delivered her nearly 45-minute speech that clinched Kavanaugh’s place on the high court, officials said.

On Sunday alone, one day after the final Senate vote on Kavanaugh’s confirmation, 8,800 liberal activists signed up to participate door-knocking and other volunteer activity related to the midterms, said Alfred Johnson, the co-founder of MobilizeAmerica.

That’s a big jump from the roughly 3,400 volunteers who signed up the previous Sunday, Johnson said.
