He, and McCain, won't get my vote for nomination. If nominated, they won't get my vote for president.
I wouldn't worry about it, as neither one will get the nod.
Guiliani could get the VP nod.
Rudy or McCain will not get my vote in any primary. But I can guarantee you if either of them is the Republican Party's nominee and Hillary is the Democrats, I will be casting a vote for either of them in the crucial state of Florida. I will not be the cause of a President Hillary.
And I hope that no one here is really thinking of sitting the 06 or 08 election out just to "show" the republican party. Because if that is the case, we will be turning our country over to the terrorists and their cohorts the Democratic Party.
