Davis' legislation "would temporarily expand the chamber to 437 seats, providing the District with full-fledged House representation while also adding a fourth district in Utah, which fell short of receiving a new seat after the 2000 reapportionment."
DC statehood = one additional Democratic seat. A fourth Utah seat = one additional GOP seat. Will it fly? Depends on the Senate provision. If it's two senators for DC, then no way...
UPDATE seems the bill addresses only the House NOT the Senate.
