OKLAHOMA CITY (AP) - Republican and Democratic party officials in Oklahoma both say they're experiencing an infusion of new party activists ahead of picking the delegates who will nominate each party's candidate for U.S. president.

      Democratic supporters of U.S. Sen. Bernie Sanders of Vermont, who won Oklahoma by ten points over Hillary Clinton, will look to elect one of their supporters into one of two "superdelegate" positions up for grabs Saturday at the Oklahoma Democratic Party State Convention in Oklahoma City.

      The Oklahoma Republican Party is holding congressional district meetings throughout April ahead of the GOP's State Convention on May 14 at First Baptist Church of Moore.

      The delegates will be Oklahoma's representatives at their respective party's national convention this summer.
