Poll: With only two days before Election Day, Trump is up by a huge margin in this swing-state

Republican presidential nominee Donald Trump has opened up a seven point lead in the battleground state of Iowa, a new Des Moines Register/Mediacom poll reveals.

According to the survey, which was released Saturday, Trump leads Clinton — 46 percent to 39 percent — among those who have already voted or who plan to vote on Election Day, Nov. 8. Libertarian Gary Johnson and the Green Party's Jill Stein registered 6 points and 1 point, respectively, in the poll.

Trump is up 3 points from the last Iowa poll, which was conducted four weeks ago. Clinton's vote share has not changed.

Currently, Clinton has a 22-point advantage with those who cast their ballot during the early voting period. However, that group of voters represents only 34 percent of the poll respondents. Trump leads by 21 points, 53-32, with the remaining respondents who have yet to vote.

Trump also leads Clinton among independent voters in Iowa, according to the poll, 41 percent to 34 percent.

The RealClearPolitics average of Iowa polls also has Trump ahead by an average of three points over Clinton.

The Des Moines Register/Mediacom poll of 800 likely Iowa voters was conducted Nov. 1-4, and has a margin of error of +/- 3.5 percentage points.
