The amnesty proposal (and its devastating impact on this country), failure to protect US borders, huge spending, the WMD fiasco, supporting McCain's pet project, the growing deaths of American's in Iraq, etc. will defeat Bush.
Maybe Bush is not interested in winning a second term and would much rather spend the time with Mexico's Fox.
If these issues don't motivate American voters to replace Bush, we may not be able recover from them for at least another 4 years.
