center but very few folks on the extremes. the red state, blue state dramatically reducing the number of competitive elections. while there were 113 crossover members of congress in '93, democrats elected in p-- it's a 77% decline, and that means there's less and less political incentive to vote across party lines while partisan media demonized moderate political differences. the backlash of president obama, the center totally hollowed out. we also have asymmetric polarization. republicans have moved further right than democrats moved left, and that tea party congress was determined to be the most polarized ever going all the way back to reconstruction. things have only gotten more polarized under president trump, the second republican in 16 years to win the white house despite losing the popular vote, something that didn't happen once in the 20th surgeon genery.
