McCarthy was somewhat right in that the administration, secret services and universities were riddled with Communists.
He may have been wrong about who exactly was a Communist or wrong about his methods, though.

What sort of evidence do you have for this assertion? As I recall, McCarthy's "evidence" was a bunch of baseless accusations made by others who were themselves accused of being Communists. The accused were promised leniency if they would only point out others who were either Communists, or Communist-sympathizers. As one can imagine, this led to a lot of innocent people being accused simply for being associated with another accused person.
And, perhaps most importantly, political ideology isn't a crime.
Still, I fail to see the similarity between Lieberman and McCarthy in this context.
Calling on companies to withdraw services from Wikileaks (Lieberman) is similar to calling on advertisers to withdraw support from Time magazine (McCarthy).
Overwrought, fear-mongering rhetoric (Lieberman) is similar to overwrought, fear-mongering rhetoric (McCarthy).
