Dems need to do what McConnell did to them. Refuse to meet with the nominee, refuse to attend any hearings, and throw up roadblocks where ever they can. They will probably lose anyway, but they need to show they can fight.
To quote Santino Corleone, “No, No more! No more meetin’s, no more discussions, no more talking.”
Also, put the Republicans on notice, from Bush V. Gore, through Heller, Citizens United, to the Merrick Garland travesty, they’ve had enough, the very first time the Democrats control the Senate, the House and the Presidency, the Supreme Court will be enlarged to a number to erase their ill gotten gains.
