'relateable' has made its way from sophomore girls to everywhere all the time. i am against it, on the grounds that that 'relate' needs the preposition ('to'). so it sounds very wrong: your need 'relatable-to,' which would itself be a nightmare. for that matter 'relate' - as in 'i relate' - was like a seventies fad, and it's not itself my favorite usage. 'connect' is better. but if you have to, i would not say 'mitt romney is not relateable,' i would say people find it difficult to relate, or rather connect, to him. or people don't like him.
