Because, as I've stated many times, my preferred stance for the state of the country would be for both the Democrats and the Republicans to be back in the hands of reasonable mainstream leadership, instead of this zoo we've had for the better part of a decade. I hate Trump, I've never voted for Trump, so the race to the bottom is no good for my tastes. I was happy when Biden won in 2020 (even though I did not vote for him), but bitterly disappointed in his administration. I want the parties to compete for the center again.
But by all means, keep pushing left. That's working great and definitely will pay dividends eventually. After all, there's nothing like an echo chamber to get stuff figured out.
