The presidential race in the U.S. is heating up as the stakes get higher. Democrat Hillary Clinton and Republican Mitt Romney have won resounding victories in their respective caucuses in Nevada.

In the Republican primary election in South Carolina, Senator John McCain gained a narrow win over Mike Huckerbee.

The Democrats hold their primary in South Carolina next week.

Paul runs second in Nevada

However, there's one man on the Republican ballot who's still to win a primary.  

Ron Paul is the renegade of the Republican Party, and is relying on word of mouth, Youtube and web sites to put his message across.

He didn't make it in the top three in the South Carolina primary. But after coming a distant second in Nevada, he still hopes for a turnaround in the race for the White House.

“What we are looking for is momentum and interest in defending our constitution, our individual liberty and limited government on different foreign policy,” Ron Paul says.

While criticised for being too radical, this message has resonated with some voters. And many are ready to follow Dr. Paul anywhere.

Critics have compared the Ron Paul following to a cult, but his supporters say such criticism is unfounded.
