Two things will distinguish the 2028 election from the midterms: first, the Democrats will have to propose an agenda of positive change to the electorate, as opposed to simply opposing Trump; and second, the condition of the country at the time of the presidential election is unknowable. I simply cannot predict the extent to which it will be necessary to use Trump’s autocratic powers to restore liberal democracy after he leaves office. As a result, the Democrats need to have a vigorous debate about their candidate and their platform in 2028, and while I would be leaning towards a centrist, I haven’t closed the door to anyone at this point in time.
The task between now and then, however, is to reimpose as many guardrails as is realistically possible on Trump. What I fear is that the progressives will make a display of opposing Trump at every turn to appease the blue base instead of picking their battles carefully to win over the electorate as a whole. The important things for the next two years are unity and effective opposition to right-wing autocracy, not publicity and pointless controversies that alienate swing voters.
