John McCain's last theoretical challenger for the Republican presidential nomination is apparently calling it quits.
Longshot candidate Ron Paul hasn't formally bowed out of the race, but he does tell backers in a video on his Web site that there is not going to be victory in the conventional sense. He says their hard work and enthusiasm have achieved many other victories. Paul says the campaign was a significant first step in a change of direction for the country.
The 72-year-old, 10-term Texas congressman campaigned on a platform of limited government, opposing both the war in Iraq and the federal income tax.
Paul became a fundraising phenomenon over the Internet, bringing in a record 6 million dollars in a single day. But he never cracked single digits in most polls.
