“the majority of their voter are abysmally ignorant and dumb as a box of rocks too.”
I don’t disagree with your assertion but I think they get elected largely because the Democrat Party encourages single issue voting. Don’t like Trump: vote for us. I’m a Muslim: vote for me. Fear climate change: vote Democrat. Feel sorry for immigrants: vote for us. Want legal abortion: vote for Democrats. These voters, sliced and diced among the issues, constitute a majority enough to elect politicians who will vote for their favorite issue but also bring a lot of baggage on other issues with them.
With regards to COVID, there was no way Trump wouldn’t have pissed half the country off, regardless of what he did.
Even the most diehard Democrat insider would tell you that before COVID he was cruising to re-election.
