Democrats and Republicans are now anxiously watching returns from seven of the nine states that will tip the balance of power in the Senate.
Democrats are hoping to pick up five seats to flip the GOP’s 54-46 majority. At 8 p.m., polls closed in New Hampshire, Illinois, Pennsylvania, Florida and Missouri. Already, Indiana and North Carolina were reporting their results.
The races showed how Republicans fought to keep their party’s nominee, Donald Trump, at arm’s length.
In Pennsylvania, GOP Sen. Pat Toomey waited until nearly 7 p.m. ET — an hour before polls closed — to cast his own ballot. Only then did he reveal for the first time that he voted for Trump. In Illinois, Sen. Mark Kirk, widely considered the Republican most likely to lose his seat Tuesday night, said he voted not for Trump but for David Petraeus.
Results are trickling in from Indiana and North Carolina, where polls closed earlier in the night.
The House is also up for grabs, but Republicans are widely expected to keep their majority — even if their current 246-186 seat advantage is narrowed.
Indiana could prove to be Democrats’ biggest disappointment of the 2016 cycle. Former governor and senator Evan Bayh’s late entry was expected to turn the state into a guaranteed pick-up — but scrutiny over his residency and lobbying work has catapulted GOP Rep. Todd Young forward.
Republican Sen. Rand Paul of Kentucky, Republican Sen. Tim Scott of South Carolina, Democratic Sen. Patrick Leahy of Vermont, Democratic Sen. Chris Van Hollen of Maryland, and Connecticut Sen. Richard Blumenthal will all be re-elected, according to CNN projections.
The presidential race has played a major role in virtually all of the key Senate contests, as Donald Trump’s controversies have put some Republicans such as New Hampshire Sen. Kelly Ayotte on the defensive. Hillary Clinton’s recent troubles, including the late focus on her email server, may have hurt Democrats down-ballot. Control of the Senate will be key to the early successes of a Trump or Clinton administration.
For Clinton, a Democratic Senate would represent a counterbalance to a House Republican conference that has fiercely attacked her on the campaign trail — even as some of its members have sought distance from Trump.
There’s also the more immediate impact: If Clinton wins and Democrats seize control of the Senate, Republicans could reverse months of resistance to confirming President Barack Obama’s Supreme Court nominee, Merrick Garland, and move quickly to approve him before Obama leaves office.
For Trump, a GOP Senate and House would, in theory, let Republicans swiftly pass legislation that reverses many of Obama’s policies.
In the Senate, Democrats need five Republican seats to get to the 51 needed for a majority. If the night ends in a 50-50 split, the new vice president would give his party the majority.
House Democrats remain frustrated with FBI Director James Comey, who made a revelation 11 days before the election that the bureau was once again looking into emails potentially tied to its investigation of Clinton. Democrats believe his announcement provided down-ballot Republicans an opportunity to shift topics and attack Clinton, rather than defend Trump.
Minority Leader Nancy Pelosi said Tuesday that Comey “became the leading political operative in the country — wittingly or unwittingly.”
Pelosi blamed Comey for costing Democrats a shot at winning Republican seats across the country, saying he created “more of an obstacle that we hope to overcome,” but adding, “it’s difficult.”
Republicans holding their own
Republicans faced a daunting task at the outset of the 2016 election cycle: They held 24 of the 34 seats on the ballot — meaning many more to defend.
But strong GOP candidates have helped the party pull some contests in presidential swing states off the board.
In Florida, Sen. Marco Rubio’s loss in the presidential primary turned out to be the GOP’s gain, as he made a last-minute decision to run for a second term rather than retiring.
Still, the map features several toss-ups.
Wisconsin Republican Sen. Ron Johnson was expected to be an easy target for Democrats, but his race with Russ Feingold has tightened in recent days.
Republican senators in New Hampshire — where Ayotte faces Democratic Gov. Maggie Hassan — and Pennsylvania, where Toomey is opposed by McGinty — could see their fates tied to Trump’s performance Tuesday.
Indiana has represented a major disappointment for Democrats. Bayh was expected to run away with the seat in a comeback bid against GOP Rep. Todd Young, but he has faltered amid questions about his residency and his post-Senate lobbying work. That race looks to be close.
Two more Republicans who were expected to be safe — Missouri Sen. Roy Blunt and North Carolina Sen. Richard Burr — have fumbled, finding themselves in much more competitive races than expected.
In North Carolina, Burr’s late fundraising start — combined with the Clinton campaign’s focus there — allowed Democrat Deborah Ross to turn the state into a toss-up.
And in Missouri, Secretary of State Jason Kander has run one of the strongest Democratic campaigns — punctuated by a TV spot that featured the military veteran rebutting attack ads from the National Rifle Association by assembling an AR-15 rifle while blindfolded. If Blunt survives, he could be the rare Senate Republican who was helped by Trump, who is expected to carry Missouri easily.
Democrats are confident they’ll pick up at least one Republican-held seat: Illinois, where Kirk appears poised to lose to Democratic Rep. Tammy Duckworth, an Iraq war veteran.
Republicans, meanwhile, are only seriously challenging for one Democratic-held seat — Nevada, where Democrat Catherine Cortez Masto is squaring off with Republican Rep. Joe Heck for the seat being vacated by retiring Senate Minority Leader Harry Reid.
Loose ends after Tuesday
Though Tuesday night’s contests are likely to make clear which party will control the Senate, there could be some loose ends to clean up.
Georgia requires its victor to reach 50%. If neither Republican Sen. Johnny Isakson nor Democratic challenger Jim Barksdale reach that mark — which is possible, with a Libertarian in the race — the two would advance to a January runoff, though Isakson would be favored in the GOP-leaning state.
In Louisiana, a “jungle primary” system means there will be a runoff in December for the top two finishers. However, whichever Republican is the highest-performing finisher Tuesday is all but certain to win that runoff.
If Clinton and running mate Tim Kaine win, his Virginia Senate seat would open up. Democratic Gov. Terry McAuliffe would appoint a temporary replacement — and a permanent replacement would be selected in a 2017 special election.
