Punishing him with prison time just makes him a public martyr, visibly suffering on nightly TV, making lots of work for half the lawyers in the country to spring him, not to mention daily interviews by his legion of media supporters.
Strip him of his citizenship (if he is found to have any), and exile him or deport him to Kenya - preferably both.
Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort [Obama's illegal and unconstitutional "treaty" with Iran].U.S. Const., Art. III, Sec. 3, Cl. 1.
The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.Id., Art. II, Sec. 4.
Too late, right? HOWEVER...
Judgment in Cases of impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States: but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law.Id., Art. I, Sec. 3, Cl. 7.
Although not convicted in office, Obama is still liable for crimes he committed while in office. Nothing about stripping him of his citizenship (if in fact he is a citizen). Let's reinstate the Constitution as the Rule of law in dealing with Obama or anyone else, and let's NOT do what the Left does by putting aside the Constitution, our Rule of Law.
If U.S. law says to strip him of citizenship and deport him, fine. But U.S. law has imprisonment as punishment for treason against the U.S.
