This seriously ill woman should withdraw from the POTUS race, on her own, or, the Democrat Party should force her to withdraw, immediately. She is healthwise, & mentally unable to perform the duties of the POTUS office!!! End of story!!!
I believe she is too arrogant to withdraw. And a switch-a-roo will only backfire on the Dems, IMO - Trump would shout that the voting is rigged (and be right).
