this is absolutely a horrible idea. next thing you'll say they spend too much time when they stand for election every 30 years so why not just make them appointed by whatever "democratic" president that is in charge
the house should be answerable to the people and have swift elections.
the major changes that should happen are reversals from the progressive disasters. we went back on the alcohol now we should go back onthings like direct election of senators. they should be s/elected in whatever manner the states deem fit for their own senator.
besides, they spend too much time f**k everyone in washington in the first place i don't know why you want them there longer
