It’s the usual play of all republicans a year before the next election: Everything democrats do must be half-assed, insincere, incompetent or bad. Any general positive action must be invalidated by quoting a specific flaw or temporary oversight, or even just an uproven assumption of it.

If for an entire year all your read is “yeah that’s good, but…” you will have a “bad aftertaste” about the candidate and party and are less likely to turn out voting for them.

And this tiny, tiny effect, applied on millions of (young) people, is enough to decide American elections.

Edit: And on the other hand, every republican action in republican spaces must be loudly applauded and praised to the skies, without any specifics. This is to instill the image that “Republicans, even if evil, get things done, while democrats don’t”
