Nothing wrong with dodging the draft for reasons the government itself decides should make you not desirable--in their mind--with being a soldier.
The only liar you mentioned, however, was Bill Clinton. He did not escape the draft by being a Rhodes scholar. He escaped it by telling the draft board he was enlisting, and they didn't follow up to find out he didn't. In those days draft boards were run by local civilians, and many of them were totally inept.
