some shopowner supports some politician...how exactly does that relate to bitcoin at all?
Overstock.com CEO not only supports Ron Paul but instead of going with the flow of the typical American sheep is enlightened enough to understand that throwing his vote away for one of the two monopoly party candidates is just an exercise in servitude. While others would deride him for "throwing away his vote" by voting for someone who will obviously not win, he wears it proudly.
Ron Paul's main campaign issue is an end to the Federal Reserve. The Federal Reserve and the world banks have their hand in just about every aspect of world economic and monetary policy.
Bitcoin also goes against the central control of the Federal Reserve and those banks.
It would be a natural thing for someone who supports Ron Paul to also support Bitcoin.
Considering overstock.com caters to hundreds of thousands of consumers and offers a wide range of products. Their accepting of Bitcoin would be huge.
There is also the fact that Patrick Byrne and overstock.com have been fighting Goldmann Sach's Merryl Lynch and others in a lawsuit for quite some time:
