Oh, Lord:
In a NYT Magazine article (referrring to possible nominees for the 2008 Republican presidential nomination):
"Nobody knows who the nominee will be that year. It could be Bill Frist, Chuck Hagel, Rudy Giuliani, Gov. Bill Owens of Colorado or somebody else -- maybe even Arnold Schwarzenegger."
Um, last time I checked Ah-nuld was born in Austria, making him constitutionally ineligible to be President (See Article II, Section 1, Clause 5 of the US Constitution).
Now, I'm sure the Democrats would love it if the Republicans ran Schwarzenegger, but I think that, despite all appearances to the contrary, the Republican Party's self-preservation instinct is strong enough not to run him.
I realise I just spent longer researching the NYT's article than David Brooks did.
