WZZM 13 will host Donald Trump's speech on air, on wzzm13.com and on the WZZM 13 Facebook page.

GRAND RAPIDS, Mich. -- Seemingly the center of the political universe, Grand Rapids will be Donald Trump's last campaign stop before Election Day -- if he makes it in time.

The Republican presidential nominee has been slated for an 8 p.m. appearance in New Hampshire, but he arrived onstage around 9 p.m. Monday, Nov. 7 -- an hour late. Trump's packed schedule likely will have him holding his West Michigan rally into the early morning hours of Election Day.

The event, technically, is set to begin at 11 p.m.

Until then, thousands of supporters are streaming into DeVos Place since doors opened at 8 p.m. Trump's running mate, Indiana Gov. Mike Pence, is slated to make an appearance with him.

The line to get into the building began forming around 9:30 a.m., with people getting in early enough to make sure they could see Trump. At other local rallies, some people told WZZM they were disappointed there was no more room.

Other people traveled as far as way as Chicago for the candidate.

Monday's event comes back-to-back to Sunday's event in Michigan, with Trump holding an event in Sterling Heights.

On the Democratic ticket, Hillary Clinton rallied her supporters on the Allendale campus of Grand Valley State University. It's estimated about 5,000 people were in attendance at her event, with many more unable to get inside because of the large crowd.

Clinton's lead over Trump in the reliably blue presidential state of Michigan has narrowed, according to the most recent Real Clear Politics poll average. It shows her ahead by 3.4 points -- off from about 12 points in mid-October -- in a four-way race.

Michigan now is considered a "toss up" state by Real Clear Politics, with its 16 electoral votes up for grabs on the candidates' path to 270 electoral votes.
