So, lets see.
Electoral College has made Senator Obama’s win official on 16 December 2008. He is now the President-Elect.
Should the USSC agree to hear, it will be sometime in 2009 after the 20 January inauguration.
If they should they declare him ineligible as not a natural born citizen. He is in office.
The USSC can not remove him as they have no enforcement authority. The Executive Branch is the enforcement authority.
Will they? I think not.
Will Congress impeach? I think not.
We may be saddled with an illegitimate president for 4 years.
Will the people in 4 years vote him out of office? That is a big unknown. If they did that would mean the Constitution and the country matter to 50+%.
Quite a scenario. No real answers, only conjecture at this point.
