A clear pattern of Ron Paul's campaign is that his staunchest critics are self-proclaimed conservatives and GOP spokesmen. This is ironic and unfortunate, because Paul, according to the American Journal of Political Science, is the most conservative congressman since 1937. As John Nichols puts it so well:
Ron Paul represents the ideology that Republican insiders most fear: conservatism.
Bucking the establishment line, in his long congressional career, Paul has remained steadfast to the Constitution. Not that there was any doubt about Paul's record, but the Constitution Party's 2008 presidential nominee, Chuck Baldwin, has aggressively supported and campaigned for Paul towards 2008 and 2012. And when Paul failed to receive the 2008 nomination, he reciprocated the support with his endorsement of Baldwin.
The fact is that when Paul espouses a limited federal government and spending cuts, he actually means it, and he has the voting record to back it up. In doing so, however, he shows his opponents to be phonies. So the knives are out.
