Not for being ineligible. For fraud, perhaps.
For any treason he's committed or will commit before such time as he's removed, definitely, at least jail.
I think we’re pretty close to meeting the burden of proof that Obama has committed and/or was party to fraud. I just get tired of the burden-of-proof strawman over the eligibility question. That burden has to be on the candidate or putative president. It’s his claim that he is eligible and so far he has not been able to support the claim with credible evidence.
