A super PAC supporting Jeb Bush's presidential campaign unveiled a new ad on Thursday promoting the former governor as "tough enough." Right to Rise's ad highlights Bush's conflict with Donald Trump during Tuesday night's GOP presidential debate. "One candidate tough enough to take on the bully," a narrator says as the ad shows Bush in a split-screen with Trump from the debate. "One candidate tough enough to take on [the Islamic State]. Jeb will destroy ISIS and keep America safe." The ad closes with the narrator saying "tested and proven leadership matters."
