The fallout from the Iowa contest in the United States presidential race was swift. Within 24 hours, Rick Santorum - 2012 winner of the Republican contest in the midwest state - pulled out after failing to connect with the religious conservatives who backed him four years ago. Kentucky Senator Rand Paul, who finished fifth among the Republican rivals, declared his campaign had run its course, as did Mike Huckabee, an ordained Southern Baptist minister who won Iowa in 2008.
The Democratic side shed a contender when former Maryland Governor Martin O'Malley withdrew, leaving Hillary Clinton and Bernie Sanders as the only two candidates left.
The field, from which will emerge the 45th American president, is a little smaller. After Wednesday, when voters in New Hampshire get their say in the protracted election process, it may shrink further.
Former Florida Governor Jeb Bush, one of the really big names in the contest for the White House, is facing a moment of truth. Despite the comfort of a hefty war chest, Bush's prospects of following his Republican brother and father into the Oval Office took a knock in Iowa where he limped home in sixth place, 20 percentage points behind Ted Cruz, Donald Trump and Marco Rubio.
Bush's failure to engage voters was apparent from the extremely poor return his financial supporters earned from an estimated US$20 million spent trying to knock Rubio's prospects. The young Florida senator gave Trump a fright in Iowa, surging to within one percentage point of the New York billionaire, and in the process hurt Bush's chances of locking in his presumptive right to carry the banner for the party's establishment.
