Byron York: While Bill Clinton rolls, George W. Bush unable, unwilling to help GOP

Bill Clinton has had his problems lately, but there’s no doubt the former president is the best booster the Democratic Party has had since leaving office in January 2001. Even now, although he’s clearly slowing down, Clinton is the party’s most effective surrogate for wife Hillary.

Republicans haven’t had the same luck. The only two-term GOP president in the last generation, George W. Bush, has stayed mostly out of politics in the seven years since he left the White House.
