Voters were saying it very loudly, the Democratic leadership just ignored them. Polls were very clear that nobody wanted either of them to run, and they both had a low approval ratings. The ticket wasn’t his to give, it was up to the voters. The Democrats chose to skip the voters, so the voters abandoned them.
I don’t see why anyone would expect voters to stick with a party that treats it’s base so disrespectfully.
And how did that work out? Did people come out to vote for the Dems?
Maybe if they had listened to the polls, the Dems would have had a candidate that people were willing to vote for in the main election
