Illinois and Ohio primaries 2024: Trump-backed Senate candidate wins Ohio primary

Rounding out our key House races in Ohio as polls close at 7:30, the Republican primary has been pretty uneventful in another Ohio swing seat: the 13th District, which Biden would have carried by 3 percentage points in 2020. Democratic Rep. Emilia Sykes will likely face either former state Sen. Kevin Coughlin or Hudson City Councilor Chris Banweg in November. Not much distinguishes the two, though: They both support Trump and share the same conservative positions on abortion, immigration, guns and more. And they both have raised only modest amounts of money: $332,000 for Coughlin, $280,000 for Banweg. Sykes, by contrast, has pulled in $1.9 million for her reelection bid so far.

Trump has endorsed only three candidates in seriously contested primaries today: Moreno, Bost and Merrin. With all three locked in competitive races, tonight's results could be a good signal of whether Trump's endorsement is as powerful as it used to be. We'll be tracking these races throughout the night.

One of today's most consequential primaries for the general election is taking place in Ohio's 9th District. According to Daily Kos Elections, Trump would have carried the district 51 percent to 48 percent in 2020. But in 2022, incumbent Democratic Rep. Marcy Kaptur defeated Republican Air Force veteran J.R. Majewski 57 percent to 43 percent here thanks to Majewski's weaknesses as a candidate: He exaggerated his military service, attended the Jan. 6 rally (though he says he didn't enter the Capitol) and once subscribed to the QAnon conspiracy theory.

Majewski quickly announced he would run again in 2024, agitating Republican operatives who feared he would once again throw away a winnable House seat. But to their relief, he withdrew from the race a few weeks ago, leaving the primary to state Rep. Derek Merrin and former state Rep. Craig Riedel. Riedel was originally the top alternative to Majewski, but a couple of his pro-Trump supporters withdrew their endorsement of him after audio leaked of him calling Trump "arrogant." That sent GOP elders scrambling to find a new alternative to Majewski, and Merrin — who was in line to be the speaker of the Ohio state House last year until a faction of renegade Republicans joined Democrats to elect a different Republican — jumped into the race just before the filing deadline.

The primary is far from settled, though. While Trump endorsed Merrin just yesterday, and Speaker Mike Johnson endorsed Merrin in January, many establishment Republicans, such as House Majority Leader Steve Scalise and Majority Whip Tom Emmer, are still with Riedel. And Merrin's late entry into the race means he trails Riedel badly in fundraising, $175,000 to $1.2 million. And while he's no Majewski, a Riedel win could still give Republicans headaches: He's aligned with the tea party movement and has previously expressed interest in joining the hardline House Freedom Caucus.

Chicagoans are voting today on a ballot measure pushed by progressives that would institute a real estate transfer tax to fund programs addressing homelessness. Today's outcome could tell us something about the strength of Chicago's progressive movement … and its unpopular progressive mayor, who's made it a policy priority.

According to publicly available polling, while Chicagoans may have started out feeling good about Mayor Brandon Johnson, their opinion quickly soured. According to Chicago-based Victory Research, Johnson's approval when he first took office in May was at 63 percent. Five months later, in October, Echelon Insights/Illinois Policy Institute found his approval to be just 28 percent, with 50 percent of voters disapproving of his job performance. By January, Tulchin Research/Stand for Children registered an approval rating of just 21 percent, with 70 percent saying his performance was "only fair" or "poor," while Echelon Insights/Illinois Policy Institute marked his approval at 29 percent and disapproval at 57 percent.

The January Echelon Insights survey also asked respondents if they approved of Johnson's handling of various issues facing the city. The mayor received the lowest ratings on "housing and homelessness" (20 percent approve, 68 percent disapprove), "management of immigrants transported to the city" (23 percent approve, 69 percent disapprove), and "crime and public safety" (24 percent approve, 66 percent disapprove).
