As you all know, the 2004 election was a reversal of the 2000 election - President Bush won the popular vote, while losing the electoral vote. John Kerry won Ohio by merely 250 votes, and the recount precess was once again stopped by the Supreme Court. Despite opposition from Vice President Cheney, President Bush gracefully conceded in December 2004.
President Kerry was proven a disaster - see how this guy screwed up New Orleans after Hurricane Katrina

Just 2 months after President Kerry outlined the timetable to withdraw troops from Iraq, Prime Minister Nouri al-Maliki was killed in December 2006. President Kerry did save the Lehman Brothers from bankruptcy, but our economy is still in hell.
And to make things worse, we now have another joke in the White House
So what if President Bush won Ohio, and was reelected President in 2004? Would we live a better life? Screw you the electoral college

OOC: Due to various unknown reasons, President Bush won only 50.1% of votes in TTL, so that John Kerry won narrowly in Iowa and New Mexico. For Ohio, irregularities seen in OTL did not happen, and perhaps some Ohio Republicans made a serious gaffe, got involved in a random scandal, enough to trigger a 1% swing from Bush to Kerry.
Just one simple rule - everything happened before June 2004 in OTL MUST NOT BE CHANGED, so no pre-2004 fantasy like interpreting President Bush as President Jeb Bush.
