Why Obama cannot (and should not) be impeached

Why Obama cannot be impeached (and should not be) by Devvy Kidd at World Net Daily (my emphasis added:

Congress cannot even impeach him because, not being the actual President, he cannot be "removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors" ... Despite all the noise out there by Obama's supporters, it is crystal clear the putative president was born with dual citizenship and is forever ineligible to be president. ... To impeach would also accomplish this: Every piece of legislation he's signed into law would remain on the books. ... Will he ever be indicted for his crimes? With enough public pressure, it can happen because his handlers would simply throw him under the bus as a liability.
