This is McCain's closing argument.
JOHN MCCAIN: "Since I've been in Washington, I've made a lot of people angry.
"I made defense contractors angry when I blew the whistle on a $30 billion dollar boondoggle and the culprits were sent to jail.
"I upset the special interests and Washington lobbyists when I passed campaign finance reform.
"I made the Pentagon angry when I criticized Rumsfeld's Iraq strategy, and I upset the media when I supported the strategy that's now succeeding.
"I angered the big spenders in Congress when I called for earmark and spending reform. No more $233 million dollar bridges to nowhere or $74 million for peanut storage in a defense spending bill.
"I didn't go to Washington to win the Mr. Congeniality award.
"I went to Washington to serve my country.
"I might not like the business as usual crowd in Washington. But I love America. I love her enough to make some people angry.
"I'm John McCain and I approve this message."
