Democrats' top line in the campaign is that they're fighting to save America's democracy. So...

1. Americans vote in primary elections.
2. American voters select Trump to be the Republican candidate.
3. American voters select Biden to be the Democratic candidate.
4. Democrat leaders try to disqualify Trump as a candidate and circumvent American voters' selection (to be replaced by...someone).
5. Democrat leaders try to rug pull Biden as a candidate and circumvent American voters' selection (to be replaced with a candidate of their own choosing).
6. Democrats' top line in the campaign is that they're fighting to save America's democracy.

What gives?
