Pro-Shannon group’s poll shows him closing on Lankford

Former Oklahoma state House speaker T.W. Shannon is making up ground in the state's open GOP Senate primary, according to polling from an allied group.

The poll, which was conducted by GOP pollster Public Opinion Strategies for the pro-Shannon group Oklahomans for a Conservative Future, shows Shannon within single digits of front-runner Rep. James Lankford (R-Okla.).

The poll shows Lankford at 37 percent and Shannon at 28 percent. Seven percent back former state senator Randy Brogdon.

A poll conducted for Lankford last month showed him ahead 47-17.

The pro-Shannon group conducted another POS poll around the same time. That poll showed a similar gap as the Lankford poll -- 51-16 in favor of Lankford. (The poll was not released at the time but was shared with Tuesday's results to demonstrate Shannon's momentum.)

Shannon recently got the endorsement of Sarah Palin but has yet to draw much big-time tea party support, despite national conservative groups disliking Lankford.

The poll shows Palin's favorable rating among GOP primary voters is 75 percent. Fourteen percent view her unfavorably.

The primary is set for June 24.

Sen. Tom Coburn (R-Okla.) is retiring.
