No - you ask yourself!! If you, and I emphasize you, want to split the party and nominate Giuliani then it is you and no one else who will be splitting the party!
I’ll not support Guiliani in the primary, but as somebody else said on a thread the other day, if Bozo the Clown is running against Hillary, then I’m voting for Bozo for President...there is a lesser of two evils, and a third party candidate is not a viable option. We’ve been there, done that, and we got Clinton for 2 terms.
You are putting the cart before the horse with your totally incorrect logic. Giuliani is probably last on my list of Republican candidates.
But if he is the nominee, then he will get my vote, and should get all of our votes as well. It is foolishness to think that splitting the Republican Party will do anything other than guarantee that we get four and likely eight more years of Bill and Hillary in the White House.
And that means, may I remind you, likely three or more Planned Parenthood-approved Supreme Court justices.
