NixGuy makes a good point here.
Bennett could have gone out as a political genius, Ohio's own Karl Rove. Instead, his accomplishments will be tarnished by the antics and ethics of Bob Taft. The reality is that Bennett's Ohio GOP operation got complacent because the Ohio Democrats are in such disarray, but I don't expect that situation to last forever.
If Bennett really were Ohio's Karl Rove he'd have been working for reform from within.
