Rationally, yes. Rats are anything but rational. Once he narrows the list to one they will descend on that one and destroy them. The question becomes, can enough Rat Senators be peeled of the pack to get the nominee confirmed in spite of the blizzard of lies the NY Slimes, et. al. will produce?
Rationally, the Dems need 40 to sustain a filibuster, and they only have 48 senators, total. Twenty five (25) of them - an outright majority - are up for reelection in 18, and ten of those are from states Trump won (including one from WVa, which Trump won by about a two-to-one margin). That is the kind of rationality that Democrats understand.And if the Republicans are able to make vote fraud harder to get away with and more painful to get caught at, that would help even more.
