OKLAHOMA CITY — University of Oklahoma President David Boren says supporters of a proposed 1-cent sales tax for public education already have gathered tens of thousands more signatures than they need to place the proposal on the November ballot.

The former Oklahoma governor and U.S. senator said Monday that he’s deeply concerned about the state of public education in the state and that Oklahoma voters who are signing the petition share those concerns.

Boren was at the state Capitol to support the nomination of Tulsa business executive Phil Albert to a seven-year term on the OU Board of Regents.

Boren says supporters already have gathered more than 200,000 signatures as they near the midpoint of a 90-day window for gathering the 123,000 signatures to put the question on the ballot.
