Was Jeb Bush SuperPAC's big advertising push in early autumn the least effective multi-million dollar advertising campaign ever?

Among presidential candidates, I think I'd go with John Connolly, who spent $10 million in 1980 (about $35 million today) and got one delegate. In state races, all the money spent against Scott Walker ($30-$50 million) failed to moved the needle, and Michael Huffington's race in California, which did nothing but foist his emasculating wife Arriana on the rest of the world.

Was Jeb Bush SuperPAC's big advertising push in early autumn the least effective multi-million dollar advertising campaign ever?

Jimmy Carter's campaign spent $50 million back in the late 70s and 1980 and a sitting President got swamped.

There are loads of losers that have millions spent by 'Political Expert Consultants' {taking a piece of the action} making sure that you can't lose. Happens every cycle.
