Bush doesn't care about the polls. That's because he's a LEADER. The Left doesn't seem to grasp this simple fact.
A ruler doesn't care about what people think. A leader does, and uses his position to persuade people he is right. By this standard Bush has remarkably failed, and has harmed his personal credibility also.
If he doesn't care about polls and alienates the electorate, they will vote against his party in the future which will compromise his effectiveness. This is the sign of a poor leader, not a strong one, no matter what FR hypnotizes itself into believing.
