The House is not a "continuing" body, which means that it must vote after each election on the rules that will govern its behavior until the next election. At the start of the 108th Congress (2003-2004), Republicans took this opportunity to change the rules in their favor. They removed an eightyear term limit for the Speaker of the House and gave committee chairs the power to delay committee votes on bills. The first empowered the Speaker, while the second empowered the chairs of the committees by allowing them to wait on a bill until support was ensured. The new rules also removed some restrictions on lobbyists that the Republicans themselves had put in place in 1995, and required "dynamic scoring" for tax bills. Dynamic scoring shrinks the apparent effect of a tax cut on the deficit by assuming that the tax cut will also boost the economy. Progressives disliked all of these changes because they worked to shut Democrats out of the policy process and to slant that process in favor of conservative supply-side ideas. They voted against it, but passed on a perfect partyline vote, 221-203.
