A lot will depend on what the Republicans do with the control. They are taking it because Washington is a deeply divided state on the state level. The Democrats have held out through their urban strongholds, but their recent blunders have hurt them deeply. it is a case of them pissing their advantage away as opposed to the Republicans siezing the heart and minds of the voting public.
Think Ohio without the high level scandals.
The GOP may pick up some seats iN Washington due to the problems the Dems have had, but the situation in Ohio iis much worse for the GOP than the Washington situation is for the Dems
Both are situations caused by the party in power, not the other side surging ahead. It's a case of "we need to get rid of these guys" not "We really need to bring in these other guys!"
Once each party takes power, and both are very likely to, they will have to do something to keep it or they could find themselves out of power very quickly.
