Behind the scenes, GOP strategists argue that Cruz contributed little of his time to the NRSC.
“Cruz might have to come to a couple of meetings in early March  but they never heard from him after that until before the election, when he cut a very generous check to the NRSC,” said one Republican source familiar with the committee.

Cruz pledged $250,000 to the NRSC in September 2014, something that angered many conservative activists.
Catherine Frazier, Cruz’s spokeswoman, noted that her boss crisscrossed the country last year to rally conservatives for Republican candidates, including Florida Gov. Rick Scott, freshman Sen. Dan Sullivan — who knocked off a Democratic incumbent in Alaska — and freshman Sen. Ben Sasse (Neb.).
