You are assuming Mitch can't get any Dem votes. If so, he's incompetent. You and Mitch are surrendering before the fight. Must be a 1955 education thing.
What Democrat votes do you think that he could get? Aside from Sen. Manchin from WV who may cross the aisle permanently, I can’t think of anyone. The Democrats are much better at keeping their side in line than are the Republicans. That’s how organized crime works.
With all due respect, “...Mitch can’t get any Dem votes...” unless and until he has something to TRADE for those votes.
A Senate Majority Leader has a few “goodies” to trade.
A Senate Minority has less to offer.
Strangely, some people seem to “think” that waiting to attack until the ammunition has arrived and been loaded is “surrender”.
