Once again Joe claimed Trump was a Democrat before he was a Republican, I guess implying he is really a Democrat. I did some research and ended up reading a Wikipedia article that discussed Trump's political positions. If accurate, Trump first registered as a Republican in 1987 then changed to NY's Independence Party. He next registered as a Democrat, returned to the Republican party, changed that to no party affiliation, and came back to the Republican party in 2012. Opportunist may be the best description.
