A super PAC aligned with President Trump plans to attack his most likely Democratic challenger in key battleground states with a high-dollar digital, television, and direct-mail ad blitz.

America First Action is using polls to track five leading Democratic candidates on their favorable to unfavorable ratings in Florida, Georgia, Michigan, North Carolina, Ohio, and Pennsylvania. These are the states they think will guarantee Trump reelection if he wins, the group told Axios. They plan to target voters through new data and have pulled hundreds of pages of research on each contender.
