What policies are the Democrats running on?

There’s a lot of talk about Biden dropping out of the presidential race, especially after the recent debate performance. There is a lot of speculation as to who might be a worthy successor as POTUS. But there are also numerous polls that show Americans feel the country is on the wrong track (71%) and are not happy with the policies Biden has pushed.

So even if they replace Biden with someone else, what would change? Right now all I hear from the Biden campaign is attack ads against Trump. There isn’t a lot of talk about what another term would do to correct the things people are disliking.

Is there a candidate that would actually address the issues? If so, who and what are their goals?

This is in the General section. I’m not looking for Trump bashing or even comparisons. I’m looking for policies the Dems are actually pushing.
