Unfortunately, political parties are about winning elections, not bettering society.

The people who support the progressive causes listed in this article really have no place to park their votes. Yes, they withdraw from election and not vote, but that is almost as good as giving Mr. Trump a vote, who, for sure, is not going to further their causes one bit. These voters really have little choice. And the people in the back Democrat rooms know that.

The people in the back D rooms also know a more aggressive stand on progressive issues is likely to create a backlash called "socialisim". If this battle cry is sounded too loudly, many soft Trump supporters (who can be convinced to stay home on election day) will have more incentive to make a trip to the polls.

If the goal is to win the election, the D's and Mr. Biden have struck a pretty good balance of "kind of promising certain things."

But it is time for USA to build a new system.
