Rep. Renee Ellmers poured some jet fuel into what was already expected a biting primary battle for North Carolina's 2nd District congressional seat.

Ellmers posted to her Facebook page a picture of her rival, Rep. George Holding, snoozing on a commercial flight.

'My opponent George Holding made sure to get another nap in after voting against North Carolina road projects, our family farms, disease prevention and even funding for our troops,' she wrote, deploying the hashtags 'low energy' and 'not for us.'

Ellmers and Holding, both Republicans who currently serve in the U.S. House of Representatives, are fighting for the same seat after North Carolina lawmakers redrew the borders this spring.

Ellmers, who came to Congress in 2010 along with droves of Tea Party-elected peers, has fallen out of step with the right-wing of the Republican party, with many now labeling her too establishment, and thus attracting a primary challenge from the right.

Ellmers' name was also entangled with that of House

She originally expected to have four primary challengers including Frank Roche, who she beat 59 to 41 percent in the Republican primary, before going on to beat Democrat Clay Aiken, of 'American Idol' fame, in the general election.

Even more threatening than Roche was Jim Duncan, the chairman of the Chatham County Republican Party, who planned to run against Ellmers.

But in February, the state's districts were redrawn by lawmakers trying to comply with a three-judge panel's ruling that two of North Carolina's congressional districts were racial gerrymanders.

Holding, who had represented the 13th District, decided to swoop in and challenge Ellmers in the newly redrawn 2nd District.

In the meantime, Roche decided to drop out.

'My ultimate objective has been to unseat Ellmers for her betrayal of 2nd District voters, conservatives and Americans across the country,' Roche wrote in a statement that announced he would not be running, according to Raleigh newspaper, the News & Observer.

'George Holding's entry into the race, a well funded and seemingly more conservative incumbent than is Rep. Ellmers, should ensure she only serves three terms,' Roche added.

The redistricting also forced Duncan not to stay in and he exited the race in late March.

'We looked at all districts,' said Duncan's spokesperson Sean Moser. 'We talked to representatives of all districts. It just didn't seem to be a good fit with what Jim was wanting to accomplish.'

'We're sure Mr. Holding is going to defeat Miss Ellmers and will have a good run in Congress,' Moser told the newspaper.

Another candidate, Greg Brannon, who unsuccessfully tried to mount a primary challenge to Sen. Richard Burr, has also joined the congressional race.

Because of the redistricting the congressional primary got moved back to June 7, while the presidential took place on March 15.

Ellmers, who said she voted for Ohio Gov. John Kasich in the Chatham County GOP Convention’s straw poll, said she actually voted for Donald Trump in her state's presidential primary, according to Roll Call.

It wasn't long before she took a page out of the Trump playbook too, labeling Holding 'low energy,' the damaging term The Donald successfully deployed against Jeb Bush.
