  This country has always fared reasonably well so it doesn't surprise me that it continued to do so under the auspices of President Bush.
The two things people will remember President Bush for are (1) 9/11 and (2) the War in Iraq. The previous statement should not be construed to mean that Bush was responsible for (1); only by heartfelt conjecture and conspiracy theory is this result obtainable. However, it should be construed to mean that Bush was responsible for (2), and this is the number one reason people are against Bush.
People don't like war, period. People hate unnecessary wars, period. The alleged reason for waging war against Iraq was that it was an imminent threat to the United States because it possessed weapons of mass destruction. So we destroyed Iraq with our massively destructive weapons. But no WMDs or evidence of WMDs were found in Iraq.
This implies to some that there were no WMDs in Iraq. If there were no WMDs, then Iraq was not an imminent threat to the United States because it possessed WMDs. Therefore the War in Iraq is perceived unnecessary, QED.
