Oklahoma Republicans did try to come to the rescue of Florida Sen. Marco Rubio in February. Rubio raised just over $175,000 in the state last month, after bringing in slightly more than $100,000 total prior to that.

Rubio finished third in Oklahoma’s GOP primary, however, and dropped out of the race two weeks later after finishing a distant second to Trump in Rubio’s home state.

Rubio’s Oklahoma donors in February included the Quapaw Tribe ($5,400), former Tulsa auto dealer Henry Primeaux III and wife Jane Primeaux ($2,700 each), state Sen. Mike Mazzei ($2,700), Oklahoma State University-Tulsa President Howard Barnett ($2,700), Tulsans Joseph, Mollie Craft and Kathy Craft ($2,700 each) of Alliance Energy, Tom, Frank and Greg Love ($2,700 each) of Love’s Travel Stops, Oklahoma City industrialist Fred Jones Hall and wife Karen Hall ($2,700 each), retired Devon Energy Chief Executive Officer John Richels and wife Charlotte Richels ($2,700 each), Devon executive Tony Vaughn ($2,700), former Oklahoma City Mayor Kirk Humphreys ($5,150) and First Assistant Oklahoma Attorney General Michael Hunter ($2,700).

Cruz, who finished first in Oklahoma’s GOP primary and is Trump’s closest challenger nationally, raised more than $118,000 in the state last month has brought in $530,182 during the entire campaign.
