Suddenly Bush is a Constitutional Stickler
I've never understood why the people of the country stand for DC residents to be without voting representation in Congress. It's completely un-American on its face. A new compromise bill that would add 2 voting members - one in DC and one in Utah (to make the Republicans not freak out) - is set to pass the House, but the White House insists they need to veto:

[T]he administration is against the bill because the Constitution limits House representation to members chosen "by the People of the several States."

"The District of Columbia is not a State," it says, adding that congressional representation for the District would require a constitutional amendment.
