If truth be told, his position on the Fed has a strong influence on the Tea Party and he has been ahead of every conservative politician when it comes to questioning government spending. OTOH, his foreign policy is not going to become reality and he is not taken seriously on that front by anyone. Why let that get to you and make you jittery when he has ZERO influence on foreign policy?
The reason he gets elected is that his opponents in the primaries are RINOs. Ron Paul, IMHO, is harmless despite his (flawed) rhetoric on foreign affairs. He is useful on the economic front. Many other RINO wannabe-Presidents are worse and cause real damage. e.g.: George Allen voted for ethanol, voted to raise the debt ceiling and triangulated his position on abortion. However, he has the right speeches for foreign policy to sway some voters who fall for emotional appeal. That is what damages the country, not empty talk on foreign policy.
George Allen? If Rick Santorum can run for Prez after losing in 2006, why not Allen? I haven’t heard his name recently, and I don’t think “macaca” by itself will keep him from the Republican Nomination.
