I am not sure I would make that conclusion. Hillary has money to burn (especially with Soros in the background). She could just be paranoid about losing a state she's ahead in.
Why would she do that if she was up by double digits?
Yeah, she’s campaigning on the last day preceding the weekend before the election... in MI.
That’s like GHW Bush campaigning in MT in the closing days in 1992.
Its over.
