I read during the PRIMARIES that Michael Cohen is a Democrat

Is that true? Hope he doesn't do anything stupid!

It looks like he flipped back and forth as practical.

Political party:
Democratic (Before 2002; 2004–2017)
Republican (2002–2004; 2017–present)

My guess is that he was a Democrat the Robert Novack was a Democrat, he lives/works in a Dem-run city and wanted to vote in meaningful primaries.
