Pundits and rivals have a lot to say about Ron Paul, but the one issue that doesn't come up is his age. His age, you say? That's the least of his electability hurdles.
Still, Paul is 76 -- four years older than John McCain when he won the Republican nomination in 2008, three years older than Ronald Reagan when he became the oldest president to be re-elected in 1984.
The issue of Paul's age was suddenly injected into the political bloodstream Sunday night when presidential historian Doug Wead tweeted: Is Ron Paul too old to run for president? The inevitable answer would seem to be yes, given the statistics and the demands of the job.
