That number is from 2013-2014, from what I've seen. Club for Growth is promising millions to Cruz, Rubio et al:
"This marks the first time the influential conservative group has called on its members to write checks to presidential candidates and coincides with a separate effort to curb the progress of celebrity real-estate mogul Donald Trump by drawing attention to its concerns with his past statements.
The five candidates for which the Club will officially bundle campaign contributions are: Sens. Ted Cruz of Texas, Rand Paul of Kentucky and Marco Rubio of Florida; Wisconsin Gov. Scott Walker; and former Florida Gov. Jeb Bush, a leading contender for the nomination who has struggled to gain traction with some conservatives."
