Voters in six states are deciding which candidates will face off in November in House and Senate races that could decide whether the balance of power will shift in the next Congress.
In South Carolina, 10 candidates were running to replace the late Sen. Lindsey Graham on the November ballot, including his sister, who was appointed to fill out the remainder of his term in July.
In Wisconsin, the storyline about the democratic socialists challenging the Democratic establishment continues to play out in the governor’s race.
Here’s a look at Tuesday’s primaries:

In Alabama, some voters decided several House races following the Supreme Court decision that limited portions of the Voting Rights Act and led several states in the South to take part in mid-decade redistricting.
Primaries were held in May, but Republican Gov. Kay Ivey pushed back those in the 1st, 2nd, 6th and 7th districts that were impacted by redistricting after the Supreme Court decision.
