Media Matters documents right-wing blabbermouth Ann Coulter's comparison of Barack Obama to Hitler:

During the April 3 edition of Fox News' Hannity & Colmes, conservative pundit Ann Coulter stated of Sen. Barack Obama: "He's a dime store Mein Kampf." Co-host Alan Colmes then asked if Obama "is a two-bit Hitler," to which Coulter responded, "[Y]es." Colmes continued: "We should be as wary of Obama as they should have been of Hitler in Nazi Germany?" Coulter responded: "If only people had read Mein Kampf."

We assume Coulter has read it many, many times.
