What do Bush's falling poll numbers mean?

Well, I agree almost 100% with this John Hawkins post at Right Wing News. He hits on a number of things that are contributing, including gas prices, the fact that foreign affairs are falling off the front page, and the resulting focus on domestic news works against Bush, etc. I do think that there is one more factor that is being overlooked, though. We have just gone through a very difficult and trying four years, followed by a highly contentious presidential election. I think Americans are both tired and content with life right now. They are not in the mood for change, and they are not in the mood for political fighting. They want a nice, quiet, "Eisenhower" period. On the domestic front, between Terri Schiavo, Social Security, and judicial nominees, they aren't getting it. I think that the falling poll numbers reflect that more than anything.
