Funny, but in all seriousness I've come to the conclusion that it's a huge mistake for the Democrats to try to play obstruction games. Practically, they don't have the votes, and it's a no win scenario for them. They'll get creamed by the right win retribution machine. On the other hand, if the appointments really turn out to be a disaster, it's Trump who's going to own it. Let people see and experience the damage he does and let him own it - especially around mid-term election time. 

Better to give the nominee a hearing and, if they really are a disaster, let it come out. And keep in mind that Supreme Court justices have a shocking tendency to follow their own mind once appointed. Remember the Obamacare ruling?
