Yes, that's fair. The Republicans are objectively worse than the Democrats, but the general dynamic is towards worsening conditions and increasing decline regardless. The Democrats at the bare minimum don't have the guts to meaningfully oppose the Republicans or do any real reforms that would make people's lives better and therefore put them in a position where they'll win consistently against the Republicans, to say nothing of doing something like tying Trump for his crimes.
In fact, I'm more partial to the position that the Democrats aren't an actual opposition party at all. They don't really object to anything the Republicans do. Rather, they focus their respective bases on culture war issues to ensure that people are distracted from the things that the Dems and GOP have a common interest in: more money and power for oligarchs, continuing and extending imperial domination, etc.
