There's actually a strong argument that the current congressional gridlock is due to representatives / senators flying into Washington Monday morning and flying back home thursday night, leaving very little time for casual conversations or backroom negotiations (which are vital to actually getting anything passed, as dirty as it sounds)
The original pattern setup might have been better, where congressmen moved to Washington for 4-6 months a year along with their families, because there was no other option. But it's harder now to do that with working spouses, and also because they would be eviscerated by challengers locally as being permanent Washington elitists.
