I think you underestimate their desperation, their infrastructure, their disregard for all rules and the American people, and their goals (either total power, or else the destruction of Traditional America... preferably both). Illegals, teens, and felons voting... misreported voting tallies (it's not who votes that matters, but who counts the votes that matters)... violence at the polling places... the MSM coordinating and guiding it all... dozens and dozens of contests that juuuust barely favor the Dem somehow... a few RINOs bribed into crossing over... they are not as far from taking both Houses as you seem to believe.
I’ve heard all that before, yet here we are.
