The place to address this issue is at the state level by requiring documentary evidence of eligibility from candidates ahead of the next presidential election.
Making it all about Obama is the wrong strategy.
Obama should be watched like a mad dog in any case.
Affirming his position as president (rather than simply _resident) makes impeachment on other grounds possible. I don’t know what the legal procedure is even supposed to be to oust a would be president who is discovered to have been ineligible. One can’t impeach a non-president. Every court up to the USSC has treated it like an untouchable hot potato.
