McCain and the War

Today on washingtonpost.com, its posted that Senator John McCain, presidential hopeful for the Republican party, supported the war in Iraq saying that it was "necessary and just." With the lowest popularity rating among the candidates, it seems as though he's taking a stance on the war to directly tackle an issue that is current with Congress/Presidential politics. McCain states that even though the country has lost patience with the on going war and the government has failed to gain the nation's trust back on the war, he feels that the fight against terrorism is a just and necessary battle.
I don't mind McCain taking a stance on the war because during these pre-election times, a candidate needs to stand out and make a name for himself. Rudy was the major of NY during 9/11. Hillary was once the First Lady and possible first female president of the US, Obama could be the first Black American to become president, and what is McCain going to be known for? Being a white collar criminal? By establishing his stance on the war, he'll be remembered for it as the elections come around.
