I've seen Obama have plenty of chances to make rash decisions, but he always seems to think before he responds, he always looks before he leaps.
McCain always seems to like to throw the dice on a 50-50 bet, Sarah Palin being the most recent but certainly not the only example.
On that factor alone I think that Obama is the better choice to repair the damage eight years of deregulation and Reaganomics has done to our financial system and ecomony.
I don't recall thinking of Perot as patient or prudent. Did he say "measure twice cut once" ?
