Rep. Ron Paul (R-Texas) said Thursday that he will make a final decision on a 2012 White House bid "within a couple of months."

During an appearance on C-SPAN's "Washington Journal," Paul said he nearly formed a presidential exploratory committee earlier this year, then backed off to think about it some more.

Paul noted that his son, Sen. Rand Paul (R-Ky.), recently said there is a 50-50 chance that he or his father will run for president.

With a laugh, the elder Paul said he would say there is a 50-50 chance that neither mounts a White House bid.

The House lawmaker, who lives with his son in Washington, said he and the senator have never talked seriously with one another about their possible 2012 aspirations.
