John McCain is now openly endorsing the policies of the Bush-Cheney White House and promising to actually continue the same policies over again? Hey, I believe in recycling but that's ridiculous.

I was in elective politics for 24 years. I've made four national races, two for president, two for vice president. I have found there are other ways to serve, and I'm enjoying them.

I'm a big fan of Bitcoin ... Regulation of money supply needs to be depoliticized.
