Anti-war Rep. Ron Paul, R-Texas, has officially entered the race for the White House.

Paul announced Friday on ABC's "Good Morning America" that he's seeking the nomination for the 2012 GOP ticket.

He first ran as a Libertarian in 1988. Three years ago, Paul unsuccessfully sought the Republican nomination.

The former flight surgeon is 75 years old, but said he believes America has caught up with his way of thinking.

"Because the time has come around to the point where people are agreeing with much of what I have been saying for 30 years," he said. "I think the time is right."

Paul represented Texas for more than 30 years. His long-standing record of cutting the size of government makes him popular with members of the Tea Party.

Still, some of Paul's positions are outside the mainstream. For example, he believes both prostitution and illicit drugs should be legalized.

Meanwhile, former Arkansas Gov. Mike Huckabee is expected to announce Saturday if he will seek the Republican nomination.
