I have to seriously disagree on the particulars, here.

The Russia allegations ranged from "Russia hacked DNC servers/accounts to interfer in favor of Donald Trump" (demonstrably true in several instances) to "Russia hacked voting machines" (very probably false). And then in 2024 the DNC quickly accepted election results.

By comparison, Donald Trump still claims that he legitimately won the 2020 elections, the majority of his base still believes it, Fox News spent years spreading that message even though their own journalists thought it was bullshit, etc.

I maintain that this is a systemic problem and a better system would not have given Trump the leeway to do this, but let's not pretend it's a bipartisan issue.
