If I were running the Hillary campaign, I would just stick with the body double.
She has been pretty much AWOL in August and September.
Some.newspaper, I think the NY Times, said that she was intentionally lying low in August. Supposedly she was happy for Trump to be out there and embarrass himself.
But the truth is likely that she was down in August with health problems. But the general public didn’t know at the time she has such health issues. Now we do.
