The ignorance of that position is multi faceted:
One, the federal government has no authority or involvement with state cases. The argument that Biden, DOJ or some secret cabal of communists orchestrated this prosecution is a fantastical lie and needs to be called out for exactly that.
Two, it is NOT a trivial or contrived matter. It goes to the heart of what Trump and his enablers have been up to since the beginning: election interference and manipulation. These felony crimes were committed to hide the truth from voters and thus influence the 2016 election to benefit Trump.
Three, there is a track record here: the numerous activities by the Russians in coordination with the Trump campaign to influence the 2016 election is well documented by the Mueller report and the bipartisan report from the Senate.
Then, as we all know, in 2020, when he lost, Trump and his enablers moved from illegal influence to trying to outright steal an election from the American voters. These actions are also well documented and supported by many sources, including the rioters themselves who acted when Trump called upon them to do so and then sat on his ass in the White House for hours as they ransacked our Capitol building.
That effort continues to this very day as Trump and others have already stated they would not trust or go along with the election results in 2024 if he loses.
If they do not understand the poison that Trump and the MAGA movement have injected into our culture, they are willfully blind.
