“With Rudy, the Republicans in Congress wouldnt really be able to oppose him, they can oppose a Rat.”
That is true, and there would be far fewer Republicans in congress to oppose anything.
When Rooty drives voters to third parties or they just stay home, the ticket will suffer from top to bottom.
Of course, the reality is that there is no way that Rudy could win the general election, while any of the others can.
