Q4: public debt, is the budget too big?

Obama slams republicans and says it doesn't make sense for them to attack his budget after the deficit that the GOP and Bush created.

Now he gets technical about the growth rate and then switches over to a bit from his stump speech. He makes the case that the US needs to make investments now in order to continue growing.

Obama slams republicans again and asks to see their alternative budget proposal...

He's doing a lot of finger pointing tonight, he's trying really hard to remind Americans that the economic crisis didn't begin with him.

Obama seems to retreat to digging into details when he doesn't have a clear answer about the economy. He needs to cut himself off, I think he's losing the audience here...
