Former Alabama Chief Justice Roy Moore is leading the Republican primary field in the race for the U.S. Senate, a new poll showed Thursday. Moore had 31-percent of the vote to Sen. Luther Strange's 23-percent. Congressman Mo Brooks (R-Huntsville) was in third place, with 18-percent. In a hypothetical runoff between Moore and Strange, Moore led by 11 points, 45-34%. The poll was taken by Cygnal, a Montgomery communications firm not affiliated with any candidate. 502 Republican primary voters were contacted by telephone Tuesday and Wednesday, a period coinciding with President Trump's endorsement of Strange. On Thursday, Moore received the endorsement of "Duck Dynasty" star Phil Robertson.
