The reason they are doing it is to counter the nazi/white supremacy rise in the US, the hatred of brown people coming up through Mexico, but it is a roundabout way, wrong to make it an issue in this election.
Just go after the actual problem, don’t start trying to scratch that wound of slavery again. It is just the wrong way going about that, especially this point in time. We have so much more the Dems need to DEMONSTRATE they are doing, even if McConnell puts them in his drawers. Furthermore, instead of talking about impeachment, BRING MUELLER TO TESTIFY IN FRONT OF CONGRESS AND AMERICA. Just create an impeachment committee, stop all other committees investigating different parts, and free those legislators, and focus on that one committee’s work, and the LEGISLATIVE AGENDA.
They are instead blathering about with warm and wooly stuff that satisfies no one but the gluten sensitive crowd.
