Forbes Magazine reported in August 2020:

It took five decades, but the Democratic Party has finally changed its stance on nuclear energy. In its recently released party platform, the Democrats say they favor a “technology-neutral” approach that includes “all zero-carbon technologies, including hydroelectric power, geothermal, existing and advanced nuclear, and carbon capture and storage.”

That statement marks the first time since 1972 that the Democratic Party has said anything positive in its platform about nuclear energy.

Here is a video from Rep. Alexandria Ocasio Cortez saying that the Green New Deal includes nuclear plants.

Note that endorsing "advanced nuclear" means supporting a new generation of nuclear power plants, in addition to those already operating (which are not "advanced").  The Democratic Party 2020 Platform also forwards the myth of using "advanced nuclear that eliminates waste associated with conventional nuclear technology."  There is no such thing in reality.  If there were, it would exist somewhere in the world.

Scientific American of August 29, 2020, reported:  "The Democrats’ 2020 platform doesn’t include a goal of eliminating fossil fuel subsidies, even though the 2016 version did."

If you like nuclear power (and its wastes and catastrophic accidents) and government subsidization of dirty fossil fuels, the the Democratic Party is for you.
