It's just after 9:00 p.m. EST (02:00 GMT) and polls are now officially closed in 15 more states, including battlegrounds Arizona, Michigan And Wisconsin.

More than a dozen states have already been projected. But as we mentioned, it's still a little too early to estimate how these results will affect the overall outcome of the election.

In addition to the presidential election, there are interesting Senate races and abortion ballot measures to watch.

In Nebraska, Republican Senator Deb Fischer is running for re-election. But polls have shown she faced a strong challenge from independent candidate Dan Osborn, a union mechanic who has served in the U.S. Navy and National Guard.

There are also some notable races to see in Arizona. There, Republican Kari Lake, who is favored by Trump, is running for a seat in the Senate against progressive MP Ruben Gallego. The seat was held by Kyrsten Sinema, an independent who decided not to seek re-election.

On the issue of abortion, Arizona voters will decide whether to amend the state constitution to expand the right to the procedure from the existing 15 weeks to include fetal viability, which is about 24 weeks.

Nebraska will also vote on two competing ballot measures on abortion — one would enshrine the right to abortion up to fetal viability in the state constitution, while the other would enshrine the current 12-week abortion ban.
