Agriculture Secretary Tom Vilsack is on the short list of Vice President candidates to join Democratic Presidential candidate Hillary Clinton on the campaign trail. Vilsack has declined to answer questions on whether or not he’s being vetted by Clinton, a move the Washington Post calls “a surefire indicator that he’s being considered.” Vilsack has been a long-time supporter of Clinton, dropping his brief campaign for President in 2007 to support Clinton’s campaign. The report calls Vilsack a well-known figure across rural America, where Democrats and Clinton have struggled. Vilsack is the only Cabinet member for President Barack Obama who has served through his entire tenure in office. Vilsack is also perceived as well-liked by both parties in Congress. Iowa Republican Senator Chuck Grassley says Vilsack would be a good pick for Clinton, and gave him high marks as head of USDA. Two other candidates for Vice President said to be on Clinton’s short list are Labor Secretary Tom Perez and Virginia Democratic Senator Tim Kaine, who campaigned with Clinton Thursday.
