What evidence do you have that that's going to be the case? I ask because my entire life, I've seen terrible things done by the Republican Party. And regular people get really hurt. For example, the great financial crisis. Yet, a little bit of time passes, and that 30-some-odd percent goes right back to voting for them.

The public voted for Republicans in their highest-ever numbers in 2020 when the party did everything possible to denigrate public health efforts and scientific research at a time when hundreds of thousands were dying of Covid, with no Mexican wall or Obamacare repeal promises met.

There is no scenario where the American vote for a party will fall below 48%, and elections will continue to be decided by how 3-4 states vote.

There is a scenario, when the public wake's up and demands the right to rank their vote.
