According to wiki 'In 2004, Smith endorsed John Kerry for president, citing the growing federal deficit and Kerry's plan to balance the federal budget.' While Smith is not a conventional politician by any means, his stated reason is something most Freepers have sympathised with. In addition he supported Duncan Hunter for President last year.
No conservative would endorse that.
Smith's endorsement of Kerry was not due to Kerry's plan; it was due to sour grapes of losing.
Smith has no principles.
