The flat but “ever-swelling field” of Republican candidates for the White House appears to be attracting even more long shots to the field, according to The Wall Street Journal.

In the last three days, former New York Gov. George Pataki and former Pennsylvania Sen. Rick Santorum announced campaigns, the Journal says, and more are coming. Those include “top-tier contenders” like former Florida Gov. Jeb Bush and “longer-shot candidates” like Gov. Bobby Jindal.

“The flatness of the field has created a “why not me?” sentiment among Republicans eying the nomination, including those contenders who have been out of elected office for years. The stampede only adds to the uncertainty, making the 2016 race one of the least predictable in generations,” the Journal says.
