Six Republicans added to progressive group's 2018 target list

The progressive group Swing Left added six new GOP-held districts to their list of targeted races where they're channeling the energy of their 500,000 volunteers to try to help Democrats take back the House — they're now targeting a total of 84 races.

Why it matters: Although all of the districts are favorable to Republicans, per Cook Political Report ratings, Swing Left co-founder Ethan Todras-Whitehill says they're seeing a surge of grassroots activists in these areas who "can move the needle to secure critical wins."
