That is awesome, you actually believe that Trump was involved in politics in the NINETEEN EIGHTIES!?!
But hey, I'll play. Post it. Find these grand political endorsements of Trump in the 1980s for whatever political office he had or was involved with or ran for or whatever courtesy of the Democratic Party and post it. In fact, find one smidgen of the slightest indication that Trump was a Democrat in the 1980s. I'll wait.
You need to catch up with American news before pretending you can talk about it.
Start with when Trump started getting active in politics, and why everybody - including the entirety of the GOP - dismissed it as a promotional prank. For his TV show.
Also while you're at it, find out who was Mayor of New York City when Trump switched to Republican. For THREE terms. And then find out whose two terms he followed. Then find out their political party. That's 20 continuous years, two decades. Then find out who was the governor of New York back when that started.
Your perception of America is way off, and it's even worse for New York.
We have lives here (in NYC), partisan is not such a big deal here as it is in the boring flyover States that are fundamentally lacking in viable hobby activities to indulge it. Or at least it wasn't, till 2017.
You can look that up too, you know.
