Pretty much the ONLY advantage that I see to nominating Giuliani is that he appears to be competitive in Pennsylvania, and the other GOP candidates aren’t. And honestly, that’s not worth putting up a pro-abortion authoritarian that will cause conservatives to stay home/vote third-party in droves. The vaulted GOP GOTV would be seriously hampered, putting states like Ohio, Missouri, and possibly even Virginia in serious danger.
If John Warner’s seat goes to a Democrat, both senators and the governor of VA will all be liberals.
