Argument: Voters do not actually choose divided government
Michael Kinsley. "McCain's Last Mistake. Undivided government won't be as bad as he warned it would be." Slate. 4 Nov. 2008 - "almost no one actually chooses divided government. Almost everyone who votes for Obama also votes Democratic for the Senate and the House. Ditto McCain and the Republicans. Divided government results when those totals are close, and just a few ticket-splitters can produce a divided result. McCain was not asking voters to split their tickets. He was urging Republicans tempted to vote for Obama not to split their tickets, for fear that undivided government would be the result."
