YOU ARE LYING. Are you aware of it? Did you actually read or hear Levin's official endorsement of Romney toward the end of the 2008 primaries? For bonus points, do you know the name of the Republican primary candidate in 2008 that Levin referred to as "my guy"?
When you have to LIE to advance your argument, respect for you is toast. I will give you the benefit of the doubt and assume that you call Levin a "RomneyBot" out of ignorance as opposed to calling him that with conscious intent to deceive.
Yep, January 2008 Levin absolutely endorsed Romney. That is a fact.
