The Democratic Congressional Campaign Committee is naming seven more candidates to its Red to Blue program, which highlights Democratic recruits who have met certain campaign goals.

The list of challengers, obtained first by Roll Call, brings the total number of Red to Blue candidates to 18. The DCCC is rolling out additions to its list more frequently and in more targeted batches than in previous cycles. The committee released its first round of picks in November.

Inclusion on the Red to Blue list helps candidates stand out to donors. The congressional hopefuls also benefit from guidance and staff resources from the DCCC. Candidates must prove they have a strong campaign and fundraising organization to be included, as well as demonstrated grass-roots support.

“Candidates are our best asset, and we will continue to do everything possible to help them build strong campaign infrastructures, energize the grassroots, and raise the resources needed to spread their message,” DCCC Chairman Ben Ray Luján said in a statement.
