However most Judges do not want their decisions questioned either - so they will most likely indeed rule in favor of such a restriction of speech in the political process.
Sadly, it was upheld by the SCOTUS back in 2003. Of course, it was the usual suspects + O'Connor that made the majority of the 5-4 split in favor of wiping their asses with the Constitution. Since then, O'Connor has been replaced by Alito- so we might hope for a better result if it somehow gets brought before the courts again.
