Because admitting so would be a blatant, proven and obvious outright lie.
Why can you not let go of a narrative that will ensure democrat control of government over the next 4+ years. The democrats could not ask for a better opponent, it is why they were funding Trump backed candidates last year. But you keep on obliterating any semblance of political power the right has while thinking you are the victim. Pathetic.
It is literally more effective for democrats to advertise republicans than it is to advertise themselves. That is how dog shit those candidates are.
