Analysis | Who'll win in Pennsylvania? Gaming out remaining votes in Oz vs. McCormick. – The Washington Post


Update: McCormick’s campaign got some bad news late Thursday: Pennsylvania’s secretary of state announced there were only about 8,700 mail ballots left to be counted in the GOP primary. The news came at the tail end of a day in which McCormick only closed the gap by about 100 votes — far shy of his gains Wednesday. That’s in part because Oz banked votes in Philadelphia, where he leads by double digits. Oz’s lead is now 1,123 votes, with significantly fewer available votes left.
The original post, from earlier Wednesday, follows.
In a move jarringly reminiscent of the 2020 election, Donald Trump on Wednesday urged his preferred candidate in the Pennsylvania Senate race to simply declare victory in a tight race before all the votes were even counted.
Setting aside for a moment how anti-democratic that is, the former president has reason to worry.
Trump-backed television doctor Mehmet Oz on Wednesday saw his lead shrink from about 2,700 votes to about 1,200, as mail-in votes that can’t be counted before Election Day and other votes were added to the tallies. And at this rate, it seems possible that former hedge fund manager Dave McCormick could overtake Oz, as McCormick’s campaign has repeatedly predicted he will.
Based on how many uncounted absentee ballots there are and the margin by which Dave has won them so far, that’s why we are confident of victory. Dave will win this race. #PASen
A little more than 20,000 votes were added to the totals in the 24 hours between Wednesday morning and Thursday morning, with McCormick gaining about 1,500 votes — in large part thanks to his superiority on mail ballots. That means that, for every 1,000 votes counted, he’s gaining about 70 on Oz. If that rate held, he would overtake Oz after about 17,500 more votes were tallied.
It wasn’t clear late Wednesday how many mail ballots remained, with estimates ranging between about 20,000 to as few as 12,000, reported overnight. There were be some Election Day ballots remaining in both Pittsburgh-based Allegheny County (strong for McCormick) and Philadelphia (strong for Oz), even as mail ballots make up the bulk of the remainder.
But McCormick’s gains thus far could somewhat undersell how much he could close the gap. That’s because he’s doing better specifically on mail ballots, which are likely to be an increasing proportion of the ballots that are yet to be counted.
McCormick is winning more than 32 percent of mail ballots, while Oz is winning about 23 percent. So for every 1,000 mail ballots (overall, not just the ones counted Wednesday), McCormick is gaining a little more than 90 votes. At that rate, he would overtake Oz after about 13,000 more mail votes were tallied.
So if the number of remaining mail ballots is closer to 12,000, Oz might hold on. If it’s near the 20,000 that his campaign estimated late Wednesday, McCormick would have a good shot at taking the lead.
Whether it will shake out that way remains to be seen. Those Election Day ballots in Allegheny and Philadelphia loom potentially large, and Oz is winning the Election Day vote overall by about a percentage point. In addition, these are statewide numbers, and the final results will depend upon where the remaining ballots come from.
For example, a big chunk of the remaining absentees is in Lancaster County, which had problems with a coding error that delayed the counting. As of Wednesday evening, Lancaster still had about 4,000 votes to be counted, and McCormick was winning them by a significantly smaller margin than he was statewide — by about 1.5 points.
But McCormick gained significantly more ground elsewhere. He closed the gap significantly late Wednesday — by about 500 votes — thanks in part to the addition of mail votes from Beaver County, where he leads Oz on mail ballots by 14 percentage points.
24 hours after polls closed Mehmet Oz’s lead is about 1200 votes – cut by more than half from his advantage early today.

David McCormick got some big numbers out of Beaver county a little while ago.
Regardless, it seems highly likely we’re headed to a contentious recount, which will mean extended scrutiny of the results, which could stretch well into next month. That’s a recipe for disaster, particularly if Trump becomes worried about his favored candidate losing after that process. In recent weeks, Trump’s candidates have lost in the Idaho and Nebraska governor’s race and in a much-watched North Carolina congressional race. And it appears very likely one will lose in the Georgia governor’s race next week, as the results in Pennsylvania continue to shake out.
Trump has already planted the seeds for crying foul over the results. And it’s difficult to see him standing aside while a state whose election results he so extensively and baselessly impugned in 2020 conducts a recount involving his candidate of choice.
And for that, the GOP would have its long-standing humoring of his baseless claims to thank.
November’s midterm elections are likely to shift the political landscape and impact what President Biden can accomplish during the remainder of his first term. Here’s what to know.
When are the midterm elections? The general election is Nov. 8, but the primary season is already underway. Here’s a complete calendar of all the primaries in 2022. Here are the results from Tuesday’s primaries: North Carolina, Pennsylvania, Idaho, Oregon and Kentucky.
Why are the midterms important? The midterm elections determine control of Congress: The party that has the House or Senate majority gets to organize the chamber and decide what legislation Congress considers. Thirty six governors and thousands of state legislators are also on the ballot. Here’s a complete guide to the midterms.
Which seats are up for election? Every seat in the House and a third of the seats in the 100-member Senate are up for election. Dozens of House members have already announced they will be retiring from Congress instead of seeking reelection.
What is redistricting? Redistricting is the process of drawing congressional and state legislative maps to ensure everyone’s vote counts equally. As of April 25, 46 of the 50 states had settled on the boundaries for 395 of 435 U.S. House districts.
Which primaries are the most competitive? Here are the most interesting Democratic primaries and Republican primaries to watch as Republicans and Democrats try to nominate their most electable candidates.
