He used to be a Democrat after a falling-out with New York's republicans. Annoying Orange's positions on policy have been fairly consistent for decades, regardless of how he was registered. There are videos of him on Oprah in the 80s talking about politics and he sounds very much like he does today, albeit younger.
If Annoying Orange loses this election, he's going back to running The Annoying Orange Organization, which means he's going back to lobbying for and making donations to Democrats behind closed doors, because Democrats get elected in his home state of New York.
