Draining the swamp was political rhetoric, just like having Mexico pay for the wall. Empty political rhetoric. It all served its purpose, to get elected.
If he ever had the intention to drain the swamp, I am 100% certain he was approached by one representing the power folks of the swamp, where Trump was told unless he wanted to be JFK'd, he and or members of his family would begin to have accidents. These people have been in power for nearly half a century, and they are not about to relinquish that power because of one man's rhetoric, even if he is POTUS.
And depending on what power group we are talking about, some have been around for centuries. The folks that control the federal reserve, and the equivalent in every western nation have been pulling the strings for hundreds of years.
The one thing all five presidents in the USA have in common besides the obvious of being white men, is that they all wanted to end what we know as the federal reserve or its equivalent. All ended up dead, and it is not a mystery.
The swamp will not be drained. That is right up there with unicorns. Com'on man!
But the corruption of men like Biden, the blatant in your face criminal corruption of the Biden Crime Family, that has to be put down, and if Trump becomes POTUS for a 2nd term, he goes after Biden and his family.
But even if the Republicans sweep everything two days from now, the Republicans will undermine Trump every other steps of the way, only allowing him small victories. Anything he wants to do that requires Congress that is consequential, don't hold your breath!. And if he goes after healthcare in the first two years, he spins his wheels again like his first year in office.
