Voters in Kansas' 4th congressional district head to the polls today in the first congressional election of the Trump era. The seat became vacant earlier this year when Mike Pompeo resigned to take over the CIA. The district covers the south-central part of the state, including Wichita. Polls are open until 7PM Central Time (8PM Eastern).
Pompeo won reelection by about 32% last November, while Trump won by 27% within the district. As the article linked to in the first paragraph notes "It’s a district that would, under normal circumstances, be considered a lock for the Republican candidate. But of course, these are not normal times, and resources are flooding into the district from left and right."
