IOWA (KTTC) -- A new Monmouth University poll shows President Donald Trump with a slight lead in Iowa but within the margin of error.
In a poll released Wednesday morning, 48 percent of Iowa voters support the president while 45 percent back Joe Biden.
Three percent are undecided and the president's lead is within the margin of error (+/- 4.9 percent).
Meanwhile, Republican Senator Joni Ernst holds a small advantage but also within the margin of error. The incumbent is up 3 percent over Democratic challenger Theresa Greenfield.
Mail-in voting is expected to skyrocket during this pandemic. Forty percent of Iowans said it's "very likely" they'll do so.
Still, 30 percent said it's "not at all likely" they will vote by mail.
