The all-or-nothing types should get the blame.
Bush would have to be a political idiot to always try to appease 5% of his base and in doing so, lose 25% of the general vote and the election. THEN YOU'LL REALLY GET BILLS YOU DON'T LIKE!
Nonsense. Bush (and any other politician) is marketing himself as a commodity. When a corporation markets a product the public doesn't want, who gets the blame for its inability to sell? The market?
The electorate responds to decisions, and in the event it responds unfavorably the blame falls squarely on the person who made the decisions.
