With control of the U.S. Senate hanging in the balance, Sen. Mark Kelly held onto a small lead over his Republican opponent.

By the morning of Wednesday, Kelly's advantage had dwindled to a single digit, with more ballots still to be counted.

Kelly, D-Ariz., was the leader in early votes. Masters had a 38 percentage point lead over Kelly by mid-morning.

There are more than 400,000 ballots left to be counted. The race resembled the toss-up many predicted in the final days of the campaign, as both sides maintained they had a path to victory.

While Masters has cut into Kelly's lead, there is still a significant gap between Masters' and Lake's support.

Lake had collected more votes than Masters.

There was a 10,000-vote gap between Kelly and Hobbs.

The Libertarian who quit the race in the last week asked his supporters to back Masters, which complicates the situation.

Victor received support from 2% of voters. He was still collecting in election day.

In a race that could come down to a few thousand votes, it still represents a potential loss to Masters of more than 7,000 votes.

Control of the Senate appears to be dependent on the outcome in Arizona, Nevada and Georgia.

In Nevada, Republican Adam Laxalt held a small lead over Democrat Catherine Masto.

In Georgia, Sen. Raphael Warnock had a small lead over Republican Herschel Walker, but election officials said it was unlikely that either man could win a majority.
