That 55% figure has been true of New York for decades. The ubiquity of public transit has historically offset the costs: since people aren’t making car payments, the portion of their income that would go to that gets spread across other spending.
I would be more interested to see figures in more car-oriented areas for a better apples-to-apples.
Many states have closed primary elections prior to the general election. So three or four candidates from the same party are campaigning against each other for the right to be the candidate in the general election, and the only people that can vote in this preliminary election are registered party members.
