Former Massachusetts Governor and 2008 presidential candidate Mitt Romney has already decided on a timeline for announcing a possible 2012 run for the White House.

In an interview with MyFox Boston Thursday, Romney insisted he had not yet made up his mind about a second run for the White House. However, the man who finished runner-up to John McCain in 2008 has already envisioned the timeframe for a possible rollout.

Asked by MyFox Boston’s anchor Kim Carrigan if he would run for president, Romney replied: “I haven’t made that decision yet. That’s something we’ll decide when we have to, which is going to be probably at the end of the year, or even a little after that.”

Romney was on the show promoting his new book “No Apology: The Case for American Greatness.”....
