Bush almost choked on a pretzel and died, we would have been stuck with Cheny as president. You can’t really vote for someone else because you think the guy may die in the next 4 years.
So if mccain gets in and dies, we are stuck with palin. If obama gets in and something bad happens, we are stuck with Biden. Biden would be a better choice if it comes down to that. But both mccain and palin are better choices than obama for president, obama sucks
