Taxes more than jobs. Leftists don’t want to pay excessive taxes any more than anyone else so Californians flood into Texas and New Yorkers into Florida. People fleeing those states because of the loony politics aren’t the problem, those will vote conservative in their new homes. The problems are from those who flee the tax hellhole states then vote for democrats because they’re too stupid to realize that’s what made their old state a hellhole.
I remember when retired lefty senator Howard Metzenbaum left Ohio for Florida to croak without paying the state death tax.
