That's interesting, as I see it as an attempt to do the opposite and add more democrat seats. "Southern California" is realistically the only one of the three with the possibility of going red. If you were to remove San Francisco from "Northern California" and place it back in "California" then I could see it possibly going red at that point.

That doesn't make sense...

This would add a net of four more Senators, which only might go Republican. Considering that California is generally considered solidly blue as it stands, this would almost certainly result in the balance shifting toward the Democrats in the Senate.

So it's essentially gerrymandering via the ballot box. Great.

Actually, it'd be more effective on the presidential election.

Right now the electoral college votes in CA are basically guaranteed Democrat votes.

This would break that, affording at least 1/3rd of them to Republicans.

That's huge, and would likely ensure a Republican president for decades.

It's basically an offer to trade a net +2 Dem. senators for some Rep. electoral votes.
