Earlier quoted context omitted.
What do you mean by saying that democrats took over the post office? I assume you mean the USPS? The postmaster general was appointed by Trump. The senate until just last week had a Republican majority. Exactly how did the Democrats exercise power to "take over"?
Dems pushed the use of the USPS as a general voting system. Terrible idea. The USPS was not designed this way. Dems knew they could leverage their population dense cities to win this using USPS. To say that one side is clean and the other is corrupt is clearly incorrect. They both cheat. They both cheat a lot. The dems just cheated better this time.
You are arguing that the Democrats cheated more than the Republicans, or "better". Do you have any evidence of this? This needs to be evidence from the past election, not Chicago in 1962 or something.
