Meanwhile, former Minnesota Gov. Tim Pawlenty is doubling down on his support for Wisconsin Gov. Scott Walker (R) in the newly elected governor's dispute with unionized public employees. Pawlenty released a statement Friday expressing his support for Walker and just yesterday released a new video and launched an online petition drive in support of Walker. But this is not the first time Pawlenty has been critical of public unions, as he has urged action in other states, penned a Wall Street Journal op-ed in December titled "Government Unions vs. Taxpayers," and appears to be gearing up to be out in front on the issue, should he run. While several potential 2012 candidates have weighed in on the recent events in Egypt and Libya, former House Speaker Newt Gingrich has been among the most consistently critical voices when it comes to the Obama administration's reaction, characterizing the response to events in Egypt as "amateurish" and recently saying "I wish the administration -- the Obama administration was as enthusiastic about democracy in Libya and in Iran and in other countries as it was in Egypt, which was our ally." Gingrich has been critical of the Obama administration's foreign policy agenda since he took office, at one point in 2009 calling it "fantasy." If foreign policy emerges as a prominent issue in the campaign, look for the former House Speaker to try to own the issue.
