Former Alaska Gov. Sarah Palin is urging Kansas Republicans to unify behind U.S. Sen. Pat Roberts, alleging his independent opponent is trying to “snooker” voters in what has become a surprisingly close race.

Palin donned an apron and flipped pancakes alongside Roberts. He once was considered a near lock for re-election but now is facing a tough battle from independent businessman Greg Orman after the Democratic candidate withdrew.

Palin is the latest GOP heavy-hitter to come to Kansas on Roberts’ behalf. Two former presidential nominees, U.S. Sen. John McCain of Arizona and former U.S. Sen. Bob Dole of Kansas, have joined Roberts on the campaign trail. Two potential 2016 White House candidates – former Florida Gov. Jeb Bush and U.S. Sen. Rand Paul of Kentucky – plan to follow.
