They called in the cavalry in SC and tried to catch their foe sleeping through a long-shot in Kansas. Not only did Oklahoma's Rep. Tom Cole openly admit that the race was "referendum on Trump", administration officials were reportedly unnerved by the amount of time and money they had to throw at a district held by the right for nearly four decades.
In the April 18 general election, state officials reported polling machines used to check in voters at one precinct in Johns Creek weren't working properly, but the problem was resolved.
Tuesday's race is expected to be a tight one, but both candidates are seemingly ready to hear the will of Georgia's 6th district voters.
Attorney David Ware said he voted for Ossoff because the Democrat defends the Affordable Care Act - President Barack Obama's signature health care law.
The Republican candidate has a slim lead in an election in the USA state of Georgia, seen by many as a referendum on President Donald Trump.
Democrats also came closer than expected in SC on Tuesday - which, Klain said, "shows there are no safe seats for Republicans and the Democrats have a broad array of districts to contest". It could also show House incumbents that they can separate themselves from Trump effectively on the campaign trail, and stave off a potential wave of retirements.
Speaking after her win on Tuesday night, Handel thanked Trump - despite being hesitant to mention him during the campaign.
After scoring their latest victories, Republicans were spiking the football.
The matchup has become a proxy for the national political atmosphere and a test of GOP strength early in Donald Trump's presidency, prompting record-breaking spending, a deluge of advertising and out-of-state volunteers, and more than a few tweets from the White House residence.
Democrats, meanwhile, were left licking their wounds. Trump said in a tweet after the results were announced. During the campaign, she criticized Ossoff for residing just outside of the district's boundaries, a charge to which Ossoff replied by saying that he grew up in the district, and moved nearby in order to live with his fiancée who is attending medical school.
"This is a heavily Republican district", Crowley said. "But these decisions aren't always made based on logic alone". Sure, it is still possible for Democrats to retake the House in 2018.

CNN called the race for Republican Karen Handel shortly after 10 p.m. ET, with her holding a lead of more than 10,000 votes over Democrat Jon Ossoff. Overall voter turnout is expected to go beyond the 190,000 who voted in April's election.
Democracy for America chair Jim Dean blasted the Democratic establishment's "unforced errors".
A progressive organizer in Georgia said the Democratic Congressional Campaign Committee, the party's campaign arm in the House, sent at least a dozen staffers to the Georgia race, including Steve Sisneros, a high-ranking DCCC official.
Democrats still must win 24 Republican seats to regain a House majority next November. Trump barely edged Democrat Hillary Clinton in the 6th in November.
Voting technology activists also are keeping a close eye on the Georgia race. Even if Ossoff loses, he's already gotten far enough to push some of his generation to consider their own role in the future of their country.
Handel told about 200 supporters: "Y'all rock".
The blog's founder, Markos Moulitsas, said in an email that the loss was "obviously disappointing". "No matter what happened tonight, we are changing the map for 2018". But torrential rain in the district on Tuesday could have a late impact on the race, especially if it snarls traffic in the region for people who were trying to make it to the polls before they closed. There are 23 districts now held by Republicans which Hillary Clinton carried last November, and some of them share similar characteristics to Georgia's 6th District - rapidly growing, diverse district that are well-educated. Rep. Joe Crowley of NY, chairman of the House Democratic Caucus, said that there are 71 districts that will be more favorable for Democrats to contest than the one in Georgia.
