I think he makes a good point about RFK and Ted Kennedy. Few seemed to think it was a problem then.
Let's remember: if enough Republicans think he'd be the best choice, he'll be the nominee. We'll worry about the Dems later. Who would be likely to beat Jeb in a primary? Senator Excitement Bill Frist? Mayor Abortion Rights Rudy Giuliani? Speaker do-as-I-say-not-as-I-do Newt?
Gov Bill Owens is best pick for President.
I think the best choice will be any candidate who will keep the Republicans from forgetting the lessons of 1992 and fracturing... leaving the path open for a moderate in name only... Democrat.
