Who cares who Simon endorses? He is and always was utterly insignificant. At least McClintock has a brain. He should stay in perhaps a few more weeks in case Arnold self-destructs between now and Labor Day (unlikely wih only "Extra" interviews), and then pull out so Arnold can defeat the Aztlan Candidate.
This crap about pulling out anytime before is ridiculous and deprives the voters a real chance to see the "major" candidates perform under pressure.... but that would certainly please certain factions that have no platform or issue stances or ideas of how best to govern, wouldn't it 8-?
