Well, the idea of spending more, is working more, which the latter is reflected by GDP. If the government spends more, it should cause more work, which should lead to higher GDP.

Now, I'm not saying that's happened, but it could be. Government spending is historically the most likely to be wasteful, in comparison to individual/retail/business spending.
