I think Biden is mostly inevitable unless he makes that major gaffe before the primaries instead of after.
Which means that Trump wins 2020, and we have to deal with four more years of this, not to mention a heavily conservative SCOTUS for years after barring us somehow taking back the senate. Moderates are banking on centrists being reasonable, while believing that they can just string progressives along with whatever they do because it's better than the alternative. "Let's return to normalcy!" they say, not realizing a lot of people want to move forward, not backward. We're counting on centrists being reasonable. If they were reasonable, we'd be talking about Hillary's re-election campaign right now, instead of Trump's.
I like how despite Biden polling better head to head with Trump more than any other candidate, him winning the primary guarantees another Trump presidency.
