If I’m Trump, I wouldn’t waste time in California. I’ll do some events in New York City, only because it is my home there anyway
That attitude is probably why you have the handle "minority Republican" instead of Majority Republican. For years and years I've been watching Rebublicans cede giant states to the Democrats like California, New York and Pennsylvania, giving them a very narrow path to the 270 EVs and very little margin for error. Then they act surprised when some mediocre candidate easily beats them by focusing on just a few swing states after having had 200 EVs basically spotted to them by Republicans who did not want to even make an effort in those states. No wonder they are the stupid party.
