In the intervening year, Iowa gave Mr. Trump his largest triumph of any battleground state: a 15-percentage-point reversal over President Obama’s easy victory here in 2012. Mr. Ameling voted for Mr. Obama in 2008, sat out in 2012 and enthusiastically backed Mr. Trump. On Wednesday, Mr. Trump called the allegations completely false. “The way it is nowadays, unless I see positive proof, it’s all a lie,” Mr. Ameling said in a telephone interview on Wednesday. Mr. Trump carried the county by 20 percentage points; Mr. Obama easily won there four years earlier.
