Candidates in five of the nation's top Senate races debate tonight — here's what to look out for in each one:

GEORGIA: How will David Perdue (R) handle questions about his business record? Perdue has been in hot water this week over his comments in a 2005 deposition that he’d spent “most of my career” outsourcing, and he didn’t help himself when he declared he was “proud” of that record on Monday. He’s had a small lead against former charity executive Michelle Nunn (D) — and how his career is litigated going forward will go a long way in deciding whether this race will keep leaning his direction.

NORTH CAROLINA: What will North Carolina Speaker Thom Tillis (R) zero in on? Tillis has hit Sen. Kay HaganKay Ruthven HaganTillis trails Democratic challenger by 7 points in North Carolina poll North Carolina businessman will challenge Tillis in GOP primary Embattled senators fill coffers ahead of 2020 MORE (D-N.C.) for her husband’s company beneftting from stimulus funds, attacked President Obama and Hagan on Ebola and hit them on the Islamic State in Iraq and Syria in recent weeks. As he looks to close what’s been a small but sturdy gap in her favor in polling, what issue will he drill hardest into to shake up the race?

VIRGINIA: Can former Republican National Committee Chairman Ed Gillespie (R) move the needle? Gillespie has been running a strong campaign — but Sen. Mark WarnerMark Robert WarnerLawmakers sound alarm on China's disinformation campaign in Hong Kong Facebook users in lawsuit say company failed to warn them of known risks before 2018 breach New intel chief inherits host of challenges MORE (D-Va.) has been even stronger, and has retained a double-digit lead in most recent polls. Gillespie could have to take some chances he hasn’t in previous meetings — without dropping his nice-guy demeanor — and land some hard attacks on Warner if he’s going to change the race.

WEST VIRGINIA: Will Republican Rep. Shelley Moore CapitoShelley Wellons Moore CapitoAmerica is in desperate need of infrastructure investment: Senate highway bill a step in the right direction On The Money: Economy adds 164K jobs in July | Trump signs two-year budget deal, but border showdown looms | US, EU strike deal on beef exports Trump border fight throws curveball into shutdown prospects MORE (R) maintain her relatively safe — but flawless — campaign? The Republican is heavily favored to pick up the seat for her party, and her only debate with Democratic Secretary of State Natalie Tennant isn't likely to change that, unless she drops a serious gaffe. Debates rarely win or lose the race for a candidate, however, and this one is unlikely to prove any different for Tennant as she struggles against the red tide of the state.

COLORADO: Does Sen. Mark UdallMark Emery UdallPoll: Trump trails three Democrats by 10 points in Colorado The Hill's Morning Report — Trump and the new Israel-'squad' controversy Colorado candidates vying to take on Gardner warn Hickenlooper they won't back down MORE (D) keep up the fire he showed in Monday's debate?
