Mickey Kaus struggles with Gropergate and explains why he held his nose and voted for Arnold. A snippet:
We know he's a pig. We're not going to love him. If he's going to keep our loyalty it will have to be by producing actual results: a slimmed down government, a balanced budget, better schools, a better business climate, etc.
And if he doesn't–hey, we can always recall him.
Kaus's rationale may explain Arnold's strong showing, especially among realistic liberals inclined to vote Democrat. His whole explanation here.
