We didn't say that we didn't THINK about it, but the time was just not appropriate. President Bush is so gracious and looked sincerely concerned. We offered polite applause for Clinton and rousing cheers for the people of Florida and the poor parents and children of Russi facing their ordeals. :) We saved all our boos for Kerry-Edwards.
I think I would not boo --- for one I don't want him to die right now because it would be too perfect for Hillary -- and she's probably already bought a nice new black pantsuit for the cameras and the timing would be right for her 2008 campaign. In fact as long as Hillary is in politics, I hope he doesn't die but hangs around making a fool of himself --- just for her benefit.
I would do nothing -- I would not cheer for him or give him any applause. You're right -- Bush is in a position to have to be polite --- but after the democrats mocked and laughed over Reagan's illness, I don't think they deserve any politeness.
