DES MOINES, Iowa (AP) — The Republicans battling to be the alternative to former President Donald Trump are coming together for what an influential Christian organization in Iowa is billing as a friendly conversation on politics and their world views. Florida Gov. Ron DeSantis, former U.N. Ambassador Nikki Haley and entrepreneur Vivek Ramaswamy will appear at the roundtable “family discussion” in Des Moines Friday, Trump is not expected to make an appearance, though he was invited. The field around Trump is winnowing with less than two months before the Iowa caucuses kick off the GOP nominating calendar. In a sign of the urgency the field faces, many of his rivals are going after each other more frequently with jabs that have often turned personal.
