Regarding the WOT, She would probably be the toughest. Reason be, she would be trying to prove that she had testicles. Otherwise (and you can bet she realizes it), she would be the LAST women elected president for the next 200 years.
That said, neither of them are suitable candidates. The primaries are important... Get behind the most suitable conservative candidate you can and squash Rudy.
You know it is one thing to be anti-Guliani. It is another thing to actually believe that Guliani is more liberal/pro-abortion than Hillary. It is quite reasonable to assume that for political reasons, Guliani had to, as a Republican in a deep blue city, adopt a pro-choice stance even if he wasn't really onboard or onboard at all. It is also quite reasonable to assume that from the time of college to the midway of Bill Clinton's gubernatorial career Hillary adopted a pro-life position for political expedience and viability in that southern state. Then as the Dems as a party fully embraced abortion Hillary was all ready to jump on board. It was a key tenet that she learned in college but knew she had to bide her time until the rest of her party caught up.
