I don't think the Dems will try to Kavanaugh Barrett. What they will do, and you can count on this, is to make the confirmation process last for a year or more. They will pull every single delay, stall, postpone, vacation, break, tactic they can think of to block the vote. My opinion is that they will not try to impune her, rather they will attempt to make it impossible to end the confirmation and vote in any way they possibly can. The idea being that the longer they can string it out, and the closer the election comes, the more ammunition they will have to say, "Wait until after the election."
