AP Decision Notes: What to expect in Alabama’s special congressional primaries

Alabama's new congressional map cuts one of the state's two majority-Black U.S. House districts, shifting the 2nd District noticeably toward Republicans (analysis suggests Trump would have carried it under the new lines).
Primaries in four districts are being held Tuesday under the revised map; both Democratic incumbents are unopposed, while the 2nd has a crowded GOP field — including Trump-endorsed Rhett Marques.
Turnout has been low in Alabama primaries and the state still lacks in-person early voting, so results will roll in at different times after polls close.
