At the end of Obama's second term, the U.S. National Debt will be $20 trillion. Annual interest on this debt will be: 1% = $200 billion 2% = $400 billion 3% = $600 billion 4% = $800 billion 5% = $1 trillion (1/4 of federal budget) Do you think the rest of the world is going to loan us all the money we want at zero per cent interest forever? Where are U.S. businesses going to get loans for expansion if the federal government soaks up all available credit? When will this bubble burst? Are you Obama supporters OK with this? Do you even care?
