In 2002, Then-Massachusetts Senator John Kerry(D) voted for the Iraq War. He later changed his mind on the war after the US failed to find WMD's. He became the Democratic Nominee for POTUS in the 2004 US Presidential Election. Because of Kerry voting in favor of the war and later coming out against it, The Bush-Cheney Campaign painted Kerry as a Flip Flopper, and Kerry narrowly lost the election to Bush 286-251.
What if John Kerry had opposed the Iraq War from the very beginning and voted against it? What changes? Does he end up winning the election? Why or Why Not?
