You have to be kidding. You think that Hillary Clinton would be better than Rudy?
Secondly, there is no question that Giuliani Presidency would be worse than Hillary Clinton Presidency for the following reasons:
1) A liberal Republican has a much better chance of getting liberal legislation passed than a liberal Democrat. Republicans aren't going generally block legislation pushed by their own President but would stop a Democrat from pushing the same legislation.
2) A Giuliani Presidency guarantees Republicans continue to lose seats in Congress and become an entrenched minority. A Hillary Clinton Presidency will result in the Republicans gaining seats and, likely, retaking Congress.
3) A Giuliani Presidency effectively makes both parties left-of-center parties, especially on social issues.
4) A Giuliani Presidency guarantees no conservative in the White House for eight years.
