That is a serious ticket. What is worse: it may, actually, elect Trump.
How so? I would think that the ticket is more likely to attract dissafected Republicans than Democrats.
I'm guessing ag believes that Hillary will need those Trump protest votes to win.
Ag has this weird belief that moderates and establishment Republicans are going to become Democrats in the future and the Sanders people will become Republicans, and that Hillary Clinton voters would just as easily vote for moderate Republicans. I feel like he only sees in black and white, so all the evil Trump and Sanders supporters get lumped into the other party, while the nice moderate heroes become Democrats.
