He exceeded the political world’s expectations by scoring a second-place finish in the race for the Republican presidential nomination four years ago. Yet as he readies a second White House run, Santorum may struggle even to qualify for the debate stage in 2016. An aggressive advocate for conservative family values, the 57-year-old Republican is announcing his presidential intentions on Wednesday, May 27, 2015.  (AP Photo/Alonzo Adams, File)
