News Information and Media Site: The waiting (in Pennsylvania) is the hardest part… and Tuesday’s other uncalled races

From NBC's Chuck Todd, Mark Murray, Ben Kamisar and Alexandra Marquez

FIRST READ: Keep an eye on how the GOP handles overtime in Pennsylvania primary

If it's Thursday… President Biden invokes Defense Production Act to address baby formula shortage… Senate confirms Biden's pick for ambassador to Ukraine… Fox News poll has Gov. Brian Kemp up big in GA-GOV primary… Sen. Bernie Sanders, I-Vt., is headed to campaign for Jessica Cisneros tomorrow in the TX-28 runoff… And Biden meets with the leaders of Sweden and Finland at the White House before he departs on his South Korea trip.

But FIRST… 1,241 votes. At our publication time, that's the margin separating leader Mehmet Oz and David McCormick in the GOP primary for Pennsylvania Senate – with 98 percent of the estimated vote in.

And how the Republican Party handles this close vote, as well as the likely recount, is the top political story we're following today.

(By comparison, mind you, Joe Biden defeated Donald Trump in Pennsylvania by 82,000 votes in 2020.)

Already, Trump has called on Oz – whom he has endorsed – to declare victory, NBC's Vaughn Hillyard reports.

But Oz hasn't gone there. Neither has McCormick, as both campaigns remain optimistic about the outstanding vote in places like Allegheny County (where McCormick has overperformed), Schuylkill County (where Oz has slightly overperformed) and Lancaster County (where they've been about even).

A hard-fought – but by-the-books – recount would remind us of how rival campaigns used to handle close counts without casting the legitimacy of the entire system aside.

Though even if Republicans get behind a clean recount now, they just voted for 2020-election denying Doug Mastriano as their gubernatorial nominee.

And remember, it's not in Trump's interest to see the outstanding count and recount go by the books, because it only draws comparison to how he and his allies behaved in 2020.

One other important point here: The Oz-vs.-McCormick overtime couldn't have come at a better time for John Fetterman and Democrats in the general election – in large part because it gives him additional time to recuperate after his stroke and surgery.

That's the current difference between the Pennsylvania Senate GOP primary turnout and Democratic turnout, with a few more votes left to count, a margin that's quite close in a key state for both parties in the fall.

On the Republican side, 1,334,369 people voted in the Senate primary, per NBC's count this morning, compared to the 1,240,593 who voted in the Democratic primary.

Lackluster Democratic turnout in Ohio raised concerns about whether voters are engaged enough there. So Democrats keeping it close in Pennsylvania could be encouraging to the party even as they run in a tough cycle.

Midterm roundup: The other uncalled races

The GOP's PA-SEN primary isn't the only uncalled race from Tuesday's contests.

In Oregon, the Republican primary for governor is still too close to call. Per NBC's current vote counts, Christine Drazan is leading a crowded field with 23.5 percent of the vote. Right behind her are Bob Tiernan with 18.4 percent and Stan Pulliam with 10.2 percent.

Also in Oregon, NBC News hasn't called the Dems' OR-5 race, where challenger Jamie McLeod-Skinner leads incumbent Rep. Kurt Schrader, 61 percent to 39 percent, though with just 51 percent of the vote counted.

And NBC News hasn't called the Dem primary in PA-12, where progressive Summer Lee is hanging on to a narrow lead over Steve Irwin in that district, 41.7 percent to 41.3 percent – with fewer than 500 votes separating them.

(By the way, PA-SEN and PA-12 could head to an automatic recount. The state's election law requires a recount if the difference between two candidates is 0.5 percent of the vote or less.)

Ad watch: Inflation on the airwaves

Wisconsin Lt. Gov. Mandela Barnes is out with his first TV ad in the Democratic race for Senate. In it, he highlights the inflation facing Wisconsin families and positions himself as the best person to fix it.

"Most senators couldn't tell you the cost of a gallon of milk. Or how much beef has gone up this year. But I'm not like most senators or any of the other millionaires running for Senate."

The second sentence is a dig at two of Barnes' top opponents, Milwaukee Bucks executive Alex Lasry and State Treasurer Sarah Godlewski. Both are partially self-funding their campaigns.

The three are competing for the Democratic nomination and the chance to face Sen. Ron Johnson, R-Wis., in the general election this fall. So far, Godlewski's campaign has spent $2 million on ads this cycle and Lasry's has spent $5.7 million. Johnson's campaign just trails Lasry's, having spent $5.1 million on ads so far.
