When gun license holders' and veterans' IDs are ok and college IDs are not, it does show political bias, especially when acquiring such IDs requires the same basic levels of proof of identity.
No it does not because as stated earlier it is the issuer of the ID that determines its validity. Gun licenses and veteran IDs are issued by a government agency while college IDs are not. There is no political bias in only accepting IDs issued by a government agency. Especially since any citizen can obtain a government-issued ID.
