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

In mid-September, Jeb Bush’s SuperPAC, Right to Rise PAC, unleashed $24 million in advertising, mostly in key early primary states — $6 million in Iowa, $12 million in New Hampshire, $4.7 million in South Carolina, and the remainder elsewhere.

Using the RealClearPolitics average as our measuring stick, Bush moved from 4.8 percent in Iowa on September 15 to… 4.8 percent today. He got as high as 7 percent on October 20.

In New Hampshire, he moved from 7 percent to… 7.6 percent today. He got as high as 9.5 percent October 18.
