From USA Today:
The Texas GOP congressman, who developed an ardent following through the Internet with his 2008 bid, is going to make an “important” announcement tomorrow afternoon in Iowa.
Earlier this month, Paul said he was “close” to making it official for another run at the GOP presidential nomination. He is among the Republicans who have accepted an invitation to a presidential debate in South Carolina, to be held May 5.
Paul has been traveling to key states such as Iowa and New Hampshire to gauge support, and recently did some fundraising for his political activities.
If Paul does announce he’s running, that means he and Gary Johnson will both be competing for the libertarian vote in the GOP primaries.
UPDATE: Paul will be announcing the formation of an exploratory committee.
