If he's going to make it bigger…

…and he is, make him pay for it. Ben Nelson has a not so novel notion...

“We didn’t have a war tax in the second World War,” Nelson said, and instead the government sold Americans bonds. ”People invested in their country, in that fashion [and] made a lot of sense back then. I don’t know why it might not make sense today, certainly in lieu of jumping to tax.”

Fair enough. If WWII's the model, bring back the 94% top marginal rate and sell all the bonds you want, though you won't need as many.
