A slew of tea party favorites are heading to central Nebraska this week to support Republican U.S. Senate candidate Ben Sasse, less than three weeks before the May 13 primary election. Texas Sen. Ted Cruz, Utah Sen. Mike Lee and former Alaska Gov. Sarah Palin will be at the Buffalo Bill State Historical Park in North Platte on Friday for a rally to support Sasse, president of Midland University in Fremont. Former Republican Gov. Kay Orr will also attend. Sasse and former Nebraska State Treasurer Shane Osborn are considered the front-runners in the race. Also running for the GOP nomination are Omaha banker Sid Dinsdale, Omaha attorney Bart McLeay and hotel owner Clifton Johnson of Fort Calhoun.
