Sometimes a misfired email is just a misfired email, and sometimes — well — there's a bit more to the story. 

The DCCC, the campaign arm of House Democrats, sent out a corrected version of a press release Wednesday morning after implying support for a candidate who is still facing off against a fellow Democrat in an unusually sensitive primary runoff. 

That candidate, Texas Democrat Lizzie Fletcher, was initially included on a press release including the organization's “red-to-blue” candidates — Democrats running in competitive red districts who receive priority support from the national group, several of whom are also locked in competitive primaries.

A corrected version of the press release, sent six minutes later, omitted Fletcher's name. 

A DCCC aide told NBC News "This was a communications staff drafting error in a press release.” 

But it's not exactly a secret that the DCCC would prefer Fletcher as the Democratic nominee in the race, rather than her primary runoff opponent, Laura Moser.

Earlier this year, the DCCC circulated opposition research against Moser, who was once quoted remarking negatively about an area of Texas. 

Despite those efforts, Moser advanced to the runoff against Fletcher, which will be held May 22. 

The winner will face Republican John Culberson, who's viewed as vulnerable and whose seat would be a prime pickup for Democrats.
