Judging from the latest email to supporters, it seems that Ron Paul really is worried about his Congressional seat:
My friend Congressmen Wayne Gilchrest (R-Maryland) was just defeated in his primary election by a neocon fraud similar to the one I face. My friend Walter Jones (R-North Carolina) is under heavy pressure as well. People like our hand-picked opponents will do anything to gain and keep power. They represent everything that is wrong with DC.
If I am defeated in the upcoming congressional primary, our ideas will be held to have been defeated as well. It will be proclaimed from the rooftops in DC that such “ridiculous and outmoded notions” as the free market, sound money, personal liberty, limited government, and a pro-American foreign policy are through.
I am determined not to let this happen. All that you and I believe in is far too important to the future of our country, and to everyone and everything we love, to let the neocons dance on its grave.
Please, help me stop the lies, the distortions, the pressure groups, the special interests that benefit from DC rip-offs. There is still time to run radio and tv ads, to set up phone banks, to get out the vote. But unless you help, my reelection to Congress may be in jeopardy. Please help me return to Congress to fight for the people of my district, and for the ideas that can save our country from the path to trouble we are now on.
I hesitated to ask you, since you have already done so much. But my wife Carol said, “When you need help, you ask your best friends.” So I do ask you, to hold out your hand in support.
According to his Congressional campaign website, he’s already raised over $ 800,000, which is a lot of money in a Congressional race, so it’s unclear what he’s complaining about.
