This is only step one. The next step will be calling off the debates. It's no longer a secret that something is wrong with Biden, likely dementia. Every single time he speaks he's more confused than the time before. The Dems know he can't be allowed to go public. The Dems are confident Biden can win. They will hide him until November and hope for the best. Pay close attention to who the VP is as that's the likely President if Biden wins.

Experience hath shewn, that even under the best forms of government those entrusted with power have, in time, and by slow operations, perverted it into tyranny.
