A neutral answer: he's a popular young conservative Jewish-American political pundit who gained fame for debates at college campuses. He gained notoriety for his snappy rhetorical "takedowns" of (mostly left-leaning) university students during open-forum guest lectures he frequently hosts on college campuses.

My personal take: his "takedowns" are pretty fun entertainment, but doesn't really have anything to do with which political position is correct or not. A lot of contemporary political ideas have a "nuanced, difficult to explain, strong" version, and a "flawed, weak, easy to explain" version. For most people, when asked to explain their political views, have trouble formulating the strongest version of their argument. Many people believe what they believe purely on emotional or tribal grounds rather than based on the facts of the matter. Ben's personal style is to find the weak version of an argument, and to (correctly) point out the obvious flaws in it. Of course, just because X argument for Y is fallacious, doesn't make Y false.
