1. He was not born in HI and he is obfuscating for as long as possible.
2. He was born in HI and he is obfuscating purposefully to keep conservatives on a wild goose chase and make them look like fools.

Not that he wouldn’t do that but this is getting serious now and there is speculation about the issue in foreign capitals. It is out of the gamesmanship area.
