Ron Paul: "it's at least 50-50 that I'll run"

So, we know that libertarian Republican Gary Johnson is almost certainly going to run for president in 2012. But what about the former Libertarian, Republican Rep. Ron Paul? The New York Times does a little profile of the 75-year-old, and comes up with this:

On Web sites for Ron Paul fans, there are urgent pleas for a father-son (or son-father) "Paul/Paul 2012" ticket. But in an interview, the senior Mr. Paul seemed taken by surprise by the suggestion of teaming up. While he is bursting-proud of his son, he is not necessarily ready to yield the spotlight: He is pondering another presidential run on his own.

"I'd say it's at least 50-50 that I'll run again," he said, adding that he would look at where the economy is. (Aides add that it would depend a lot on what his wife, Carol, says.)

Paul had recently told The New Republic that he will "most likely" throw his weight behind Johnson, and that "I can't imagine endorsing anybody else." Commenter-bait: Which of the four possible scenarios (Paul & Johnson both run, neither of them run, or one of them runs) would you prefer, and why?
