Former U.S. ambassador to the United Nations John Bolton said Thursday he wouldn't run for president, which means the 2016 race remains free of mustached candidates. But Democratic digital director Rob Flaherty tweeted a photo of Marco Rubio with Bolton's trademark white 'stache with a link to an article arguing Rubio's foreign policy is a "rerun." @TheDemocrats account later tweeted six other Republican presidential hopefuls with the mustache, saying even though Bolton isn't running, "his ideas are."
