Mark Salter, who was a top adviser on the 2008 presidential campaign of Sen. John McCain (R), is not a fan of Wisconsin Gov. Scott Walker (R).
On Thursday, Salter went on Facebook and posted an article criticizing a comment Walker made about the Islamic State jihadist group (also known as ISIS or ISIL) at the Conservative Political Action Conference. Salter added a colorful comment.
"I want to like him but Scott Walker is kind of a dumb ass," Salter wrote.
During the 2008 race, Salter became known as an outspoken staffer who sent reporters colorful missives Politico dubbed "Saltergrams." He did not respond to a request for comment about his post from Business Insider.
At CPAC, Walker pointed to his experience weathering massive protests against his administration when he was asked how he would handle ISIS if he were president.
"We need a leader with that kind of confidence," Walker said. "If I can take on 100,000 protesters, I can do the same across the world."
Walker is a top Republican contender in the 2016 presidential election. In recent weeks he has gone from a relative dark horse to leading several polls.
