Look at these clips from Paul Ryan speeches back in 2002, proving that Ryan was for Keynesian stimulus spending before he was against it. Some would call this hypocrisy. But maybe it's just that Republicans support spending and deficits during Republican administrations, but denounce them as the devil's handiwork when Democrats hold the White House.
To be fair to Ryan, I have read that he was not all that happy with the explosion of debt during the Bush administration that resulted from lots of new government spending and enormous tax cuts. That would mean he was just being a good soldier by advocating the Bush administration's positions in 2002. If that's the case, can we trust anything he is saying now?
