The guy won by a embarrassingly low margin in New Jersey in 2006 against a no-name
His opponent was the son of the most popular governor NJ has had in my lifetime who had built his own career in the state senate. He may not have been a very strong candidate, but he was one of the strongest possible candidates for NJ Republicans, and his name was his #1 asset.
Tom Kean Jr. was a stellar candidate ... on paper. In practice, he was lackluster. A case of a really smart guy putting too much trust in some not-so-smart advisers.
He's currently State Senate Minority Leader, and from what I hear, he does a pretty decent job at it.
Their congressional Delegation is pretty good.
The point was that none of them will actually run. Though I'll say that Leonard Lance would make a stellar candidate ... on paper.
