Cali will allow thousands and thousands maybe millions of illegals to vote in 2020 throwing the national election into turmoil. Watch and see. California makes a disaster of 2020 election.
Fortunately we don’t have a “National (majority) vote.” It won’t matter if California allows 15 million fraudulent votes, since they’re only responsible for their 55 Electoral Votes. Trump will sweep a majority of those elsewhere on Election Night.
(Still, California’s votes should be nullified for obvious epic-level fraud)
The 55 electoral votes will go for the Democrat. The two senators are both Dems already. I don't see the effect at the federal level.
