Guiliani wants to run for president. He can't run the risk of losing to the Hildabeast and then running against her for president. Remember the presidential campaign would begin within a few months of the senatorial election, back-to-back campaigns would be incredibly difficult.
Then again, it worked out well for Abraham Lincoln (although I have a feeling that the campaigns were a little easier back then).
