And it looks like the number of votes in the Congress will in fact be changing. On Tuesday, the Senate achieved cloture (broke a filibuster) on S.160, the District of Columbia House Voting Rights Act of 2009, which would (1) permanently expand the size of the House from 435 to 437 members and (2) give one of these additional seats to the District of Columbia. This measure is quite likely to formally pass the Senate soon, be followed up with a vote in the House, and be signed by the President. Unless it is struck down on a Constitutional basis (and it will certainly be challenged), it will become the law.
