Rick Santorum To Announce On May 27th

If he enters the race as most expect him to do, that will bring the 2016 GOP field to seven: Rick Santorum, Rand Paul, Mike Huckabee, Carly Fiorina, Ted Cruz, Marco Rubio, and Ben Carson.

Still to declare: Chris Christie, George Pataki, John Kasich, Jeb Bush, Bobby Jindal, Lindsey Graham, Rick Perry, Donald Trump, and Scott Walker - all of whom have registered exploratory committees or formed 2016 campaign PACs.

Of these 16 declared or potential candidates, who do you find least objectionable?
