... Propaganda is just as dangerous as a voting machine hack...
We disagree on that one.
Whether it is a disadvantage or not remains to be seen. Half of the population would cheer it, the other half jeer it. Democracy rests not on some supreme power feeding only truth to the masses, but on the masses' ability to discern what is what. If they can't, they deserve what they got.
On a side note, I do not really see what the Ukraine investigation would achieve. Biden admitted what happened publicly, so the American voters already have all they need to know. No need for investigating him on that. As gaffe-prone as he is, I doubt that he is that stupid to leave a written document somewhere in Ukraine saying: "fire that SOB for investigating the company my son is on the board with."
What an Ukrainian investigation might be about is to find internally what led to dropping the case against Burisma (well, even that is clear, Biden's pressure) and more importantly, if the reason for firing the original prosecutor was indeed corruption, why the next one did not continue or reopen the case?
