I didn’t say 330 million registered voters. I said 330 million people, as in total population of the country including all nonvoters and ineligible.
At any rate, I don’t think any singular factor dominated, each person has their own mix of issues. Economy was a big one, including things like rent prices that the feds have little control over in our system. Gaza was a smaller one, definitely. There’s at least a dozen more.
Polls cannot really accurately capture this, they’re too clumsy a tool. Focus groups can though.
You don’t need that propaganda line anymore, you already won. Or did you actually start to believe it?
