State governments who control the redistricting process every 10 years, have also perpetuated the polarization within Congress, experts say.
"The way the House is gerrymandered, without a huge wave election, you won't see a change in the House," says DiNiscia. "Gerrymandering is at the root of this problem and under our Constitution, it is a matter that is dealt with state by state."
The good news, is that in the Senate, the statewide nature of the elections has led to more moderation and more compromise. The Senate managed to avoid a filibuster fight through negotiation and sort out a comprehensive immigration bill that garnered bipartisan support.
DiNiscia says it is not necessarily even a bad thing that Congress moves at a glacial speed and that they manage to do so little, passing just 21 bills in their first 200 days.
"It is a good thing when Congress takes its time. The problem has been that it is going slowly, but not effectively," he says. "The Constitution was enacted so Congress did not run roughshod and infringe on civil liberties, but now it seems like a mess."
