I read about that a couple of days ago... I think its absolutely the height of bad taste, but supposedly Nancy Reagan is a fan of McCain's and not endorsing him officially, but it surprises me that she is allowing this..
McCain hasn't clenched this nomination just yet - we could still broker a different guy at the convention (unlikely, but it has happened in the past) and using Reagan in any way is just wrong. For any of them.
I'm sick of the Reagan comparisons. We got one Reagan and we aren't likely to get another one, especially with the career politicians we have right now.
