With all due respect, Jim, the Pennsylvania results had nothing to do with national issues but was pure voter outrage over a sneaky and in fact unconstitutional pay raise for these very same legislatures pushed through with "bi-partisan" support in the middle of the night. The public outrage was strong enough that they eventually rescinded the raises but incumbents in both parties are facing voter rage because of it. Even the Democrat state house member from my heavily Democrat district who for 20 years now has usually won by 60-65% margins only won his Democrat primary by less than 200 votes.
Republicans and Democrats are equally pissed at the state House & Senate.
I think the overall disatisfaction with how we are being represented definitely spills over onto the national level. The signal we sent was meant to be seen as far away as Washington.
