[concerned about politics]

Given three flawed candidates, will conservatives vote for McCain? Or will they just sit out the primaries, or dissipate their votes on secondary candidates?

They won't vote, or they'll vote for a Conservative of a third party and hope the moderate Republicans and libertarians will join them.

Why would a Conservative, either fiscal or social, vote for Rudy?

I don't know about conservatives, but a patriot would vote for Rudy because the imposition of Sharia Law on America would be unthinkable to him. I really believe that any Democrat running would bring defeat and Sharia law closer.
