Judges, taxes, the war, security and so forth would be in better hands with any running Republican over the Democrat candidates.
No sense in getting your worst enemy elected because there isn’t the perfect Republican candidate.
No sense in getting a republican elected if they aren't substantively different than the democrat
AFAIC there are very few candidates of either party who are worse enemies of conservative principles and ideals than Giuliani and his ilk. I won't vote for a two-faced pro-abortion, anti-2nd Amendment, pro-"gay marriage", anti-family values liberal just because he or she has a capital R listed after his or her name.
If the slide into liberalism by the Republican party isn't stopped here and now there soon will not be an organized party left to counterbalance the Democrat libertines and Marxists who dominate the other major party. At some point very soon the conservatives, both social and fiscal, who still remain in the GOP must do whatever it takes to shake out the liberal trash that has accumulated in the party, and start nominating and electing both social and fiscal conservatives who represent what the party has stood for until very recently since it's last major renovation by Reagan and his supporters in the early 1980s. When our top ranked candidates in the polls are equally as liberal as the Democrats' candidates and our lowest ranked candidates are the most conservative of the bunch, it's very clear that something is rotten in the party and that rotten deadwood must be kept from gaining a major position of power in the party organization if conservatism is to even merely survive in the party, much less to dominate.
If it requires losing an election and suffering through 4 years of a Democrat administration to stop the GOP's downhill slide into me-too liberalism, then that's the price we will have to pay for allowing ourselves to be duped into choosing RINOs such as Rudy and Arnold to play such important roles in the party in the first place. I spent 2 decades in a GOP which was run and dominated by northeastern country club liberals, and if that's what the party is returning to I won't remain in it and support it's liberal candidates for another election cycle, much less another decade.
