On March 20, 2010, West Virginia Republican Party chair Doug McKinney referred to Oliverio's conservative political leanings by saying, "Sen. Oliverio has always been a conservative guy. He votes with the Republican on committees. We've joked for years he needs to come over to the party who thinks like he does."
