The Debt WAS a problem before Obama. We used to complain about it under Bush, too.
Obama has just managed to expand it so fast (added $6 trillion to it in less than a single term!) that it is become absolutely vital.
Anytime a freeper would mention Bush’s defiicits and huge over spending they were called trolls from DU. This was before the dem congress was sworn in before 2007 too. Either the budget busting measure were excused as pragmatic strategy maneuvers or excused for nation building in the Middle-East, go-go-go big spending Republicans I guess :-(
