Yes, that is the reason.
Democrats have the population centre and they’ve created policies to drive out wealth creators, leaving Republicans, who still outnumber Democrats, but are too spread out to be able to do anything about it.

Republicans, who still outnumber Democrats, but are too spread out to be able to do anything about it.

When it comes to statewide races, republicans should control the governor's office and the state senate and state house, but they don't. Republicans should also be in control of the 2 senate seats in Washington, but they don't. If they have the majority statewide, being spread out has nothing to do with it.
