He's back—though GOP presidential candidate Ron Paul never really left. (See his showing in the Pennsylvania primary, where, against presumed nominee John McCain, he picked up nearly 16 percent of the vote despite having effectively suspended his campaign months ago.)

Today, Paul's book, The Revolution: A Manifesto, is officially released and it's already zoomed to No. 8 on Amazon's bestseller list and is the top-selling political book. The Texas congressman is using today's launch to urge his fervent supporters to continue their libertarian "revolution."

In a message to supporters this morning, Paul says that the rest of American has "underestimated you," and urged them to descend on book stores to pick up "what my friends are calling..."Ron Paul's legacy."'

What he's also looking for are book proceeds, of course, to "fuel our revolution for a long time to come."
