The final presidential debate is set for Wednesday night, and the brave person who has volunteered to wrangle the candidates is Chris Wallace.

Wallace, the 69-year-old host of "Fox News Sunday," is a registered Democrat — but don't expect him to go easy on Hillary Clinton. He has said he doesn't want to get involved in the nominees' discussion. 

"Basically, you’re there as a timekeeper," Wallace told fellow Fox reporter Bret Baier this week, the Hill reported. "But you’re not a participant. You’re there just to make sure that they engage in the most interesting and fairest way possible. And I take it very seriously."

Wallace has been at Fox News for 13 years, but he's covered decades of presidential elections, including those in 1980, 1984, 1988, 2004, 2008 and 2012, according to his bio. He helped moderate the first Republican primary debate last year with Baier and Megyn Kelly.

The Commission on Presidential Debates chose Wallace to oversee this last debate — and refused to switch him out despite protests from Clinton supporters who argued it was unfair for a moderator to be tied to Trump adviser and former Fox News CEO Roger Ailes. 

He's insisted in the past that, despite Fox News' reputation for being a conservative network, he is objective. "We're providing fair and balanced coverage, and part of that is because many of the other networks are tilted to the left, and we provide both sides of the story," he told the Hollywood Reporter in 2014. "I defy anyone to watch 'Fox News Sunday' and say the show tilts right or left. We're equal opportunity inquisitors."

Wallace himself chose the subjects for the final debate. The commission announced them last week: debt and entitlements, immigration, the economy, the Supreme Court, foreign hot spots and fitness to be President.

The faceoff is scheduled to begin at 9 p.m. EDT Wednesday.
