The author of the letter, "Negative attacks on President Bush backfired on the Democrats," must not have heard all the very negative ads and words about the president's opponent. The campaign tactics of the Republicans made it very difficult for the Democrats and others not to strike back, which is unfortunate.
I think he is also confused about the war in Iraq. Bush told us that we made a pre-emptive attack on that country because it had weapons of mass destruction. That has proven to be wrong.
It is possible that we may never catch those responsible for planning the attack where "3,000 innocent citizens went to an early grave" precisely because the president focused on Iraq rather than the people who perpetrated this crime. Bush was talking about going after Saddam Hussein prior to his election in 2000, long before the attack on 9/1 1.
