Wisconsin Gov. Scott Walker (R) was in New Jersey last Tuesday and hinted that he is still eyeing a 2016 presidential run.

According to the National Review, Walker was at a lunch at the home of one of his mega donors when he took nameless swipes at two potential contenders on the Republican side -- Sen. Rand Paul (Ky.) and New Jersey Gov. Chris Christie.

Walker mentioned how he lowered property taxes in Wisconsin, while Christie has not been as successful on that issue in New Jersey.

Walker spoke on foreign policy as well, saying he thinks the reason "young voters are suspect about foreign policy and the wars and many things like that is that they just haven’t been properly administered.” Paul is relatively isolationist in his views on foreign policy.

Walker also spoke about former Secretary of State Hillary Clinton, telling the crowd that “you gotta move it from a personality race, because if it’s a personality race, you got a third Clinton term.”

“The only way we win that election is to transform her personality to Washington versus the rest of us. Senator Clinton is all about Washington, everything about her is all about Washington,” he added.

Walker is often mentioned as a viable 2016 GOP presidential contender and came to prominence in 2011, when he took on labor unions in an anti-collective bargaining push. In 2012, he survived a Democratic attempt to recall him from office.
