It isn't. That's the point.
If all we do is vote every 4 years, complain about the results for a week, then go back to our lives and vote again 2 years later, nothing changes.
If your car was down a quart of oil, you would add a quart to fill it. If your car lost a quart of oil every week, would you keep putting more oil in it, or would you investigate why it was losing so much oil?
You don't fix a corrupt voting system by voting anymore than you fix a massive oil leak by adding more oil.
So voting for one over the other, in and of itself, makes ZERO difference.
So this is why I'm always confused when people say, "get off your porch" in reference to someone stating that they prefer DeSantis over Trump. It's nonsense.
And a person is just as likely to do nothing about securing elections whether they vote for Trump or DeSantis.
