One of the many things that the Democrats and third world banana republic regimes have in common is that they arrest their opposition on bogus charges.
It's the dirtiest form of politics that there is.
Democrats aren't prosecuting Trump. Republicans are, just like the Republicans prosecuted Richard Nixon. And for far worse crimes than Nixon. Nixon didn't commit treason, or take bribes from foreign governments.
One of the things Republicans have in common with other thugs is that they consistently think they are above the law or that they won't get caught. First Richard ("I am not a crook!") Nixon, and the Watergate coverup. Then almost the entire Reagan Administration and their Iran-Contra scandal, which went against the laws of the United States to sell guns to Iranian terrorists. I guess the Democrats should let these things slide.
Now you have a President who is openly obstructing justice, dangling pardons to his friends who refuse to cooperate with the Special Counsel's Investigation, and threatening his political enemnies with FBI investigations. And an old school Republican prosecutor who is dotting all of the i's and crossing all the t's on his way to recommending the Impeachment of the President of the United States for high crimes and misdemeanors.
