Answer: Biden being unpopular doesn't mean Democrats can't win
I think my main takeaway is that you can look at all of the issues that might look bad for Democrats — from Biden's low approval to voters worrying about immigration — and it just doesn't mean that Democrats can't win. There are so many forces at work. Voters are motivated to vote against Trump and the party that supports him, and see the Republican party as extreme on some issues, like abortion. It's something to keep in mind as we head into November. But otherwise, I agree with everyone else. Tonight was just one special election.
