FILE - In this Nov. 1, 2011 file photo, Republican presidential candidate, Rep. Michele Bachmann, R-Minn., speaks in Pella, Iowa. To hear some Republican presidential candidates tell it, the president?s pen is a magic wand that can make Obamacare vanish in one day and sweep in cheaper health care, economic growth and lots of jobs in businesses freed from the health care law?s heavy hand. But there is no such fairy dust in Washington. Across the board, the contenders pledge to repeal the overhaul. In doing so, some are more realistic than others about what they can achieve and how fast. (AP Photo/Charlie Neibergall, File)
