Mick Cornett raised more money from donors than his rivals for the Republican gubernatorial nomination, but Lt. Gov. Todd Lamb and Tulsa businessman Kevin Stitt maintained their cash advantage after the first three months of the year.

Cornett, the former Oklahoma City mayor, collected $439,000 from Jan. 1 through March 31, and ended the quarter with nearly $800,000 in his campaign account, according to a report filed Monday with the Oklahoma Ethics Commission.

Stitt collected nearly $422,000 from donors, and put another $400,000 of his own money into the campaign. He finished the quarter with $1.6 million., Lamb received $330,000 in the quarter and had $2.4 million on March 31.

Cornett's cash on hand was up from $660,000 at the end of December. Lamb's available cash was down from $2.6 million, while Stitt's was the same at approximately $1.6 million.
