Margiotta made the comment at a Summer Leadership Conference of the Greater Raleigh Chamber of Commerce in Greensboro.
On the phone Thursday, Margiotta said he's not a hundred percent sure he won't run, but said he doesn't think it will be necessary for him to run when election time comes.
Margiotta said the comment wasn't the most important issue in his speech. He said the most important issue was the need to put the diversity controversy behind and improve schools in the county.
Margiotta is 72. His school board district includes parts of Cary, Apex, and Holly Springs. Before last fall's school board elections, Margiotta often found himself in the minority on many votes.
But since a new majority was voted in last November on an ant-busing neighborhood schools platform, he's taken the lead in pushing through the new agenda.
