President Trump has endorsed one of the Republicans, John Cox, which could give Mr. Cox enough votes to win the other slot. Given how overwhelmingly Democratic the state is — and Mr. Cox’s ties to Mr. Trump — that result would no doubt result in many people declaring Mr. Newsom the presumptive next governor.
But if Antonio Villaraigosa, a Democrat and former mayor of Los Angeles, wins that second spot, look out for a competitive, classic North-South battle.
Here’s the latest:
• Polls close Tuesday at 8 p.m. Pacific time. California is a notoriously slow state when it comes to counting ballots, but we expect to get a reasonably early projection of the top finishers in the races for governor and Senate.
• Candidates made a last-minute scramble for votes on Monday. In the governor’s race, Mr. Villaraigosa traveled around Los Angeles, ending up with a late-night stop at Pink’s Hot Dogs. Mr. Newsom greeted voters at a diner in Inglewood before heading to San Diego and San Francisco. Mr. Cox showed up at a candidate telephone bank in Riverside County.

Who will get the blame if Democrats get locked out?
Tuesday is Election Day, which means Wednesday is — depending on the results — Blame Day. The big question: If Democrats get locked out of competitive Republican-held congressional races — a distinct possibility in three districts because of California’s nonpartisan top-two election system — who gets the blame?
Here are some nominees:
The Democratic Congressional Campaign Committee, for lurching from candidate to candidate in some of these districts (until the end), giving voters little help in navigating ballots swimming with the names of mostly unknown Democrats who want to go to Washington.
The California Democratic Party, for failing to groom a bench of candidates for this moment — and for its largely unsuccessful efforts to clear the field.
California’s nonpartisan top–two election system. This election reform may end up producing the worst-case scenario Democratic and Republican leaders warned about when it was passed by voters in 2010. With so many candidates jumping into the open primary, Democrats are fighting over a set number of voters.
From this point of view, there was little state or national Democrats could do. (And it is not just Democrats. Republicans could get locked out of the November ballot in the governor and Senate race.)
Voters, for not figuring out this somewhat overwhelming ballot. (But no. Rule of thumb in politics: Never blame the voters.)

California offers clues for the nation.
The quirks that make the California primary risky for Democrats also make it a leading indicator of the general election.
In California’s nonpartisan top-two system, voters can cast a ballot for any candidate, regardless of party. Historically, that means these top-two primaries look a lot like the general election.
Since 1990, the major party vote share in top-two congressional primaries in Washington State and California has differed from the general election result by an average of three percentage points, an Upshot analysis shows.
That mans the California results will be about as good as any data we are going to get before November. The average House poll over the final three weeks of an election is off by an average margin of 6.2 points, according to FiveThirtyEight. The primary results are a bit like getting a free round of 52 final House polls in early June.
The results are good enough that you can put stock in a surprise. In 2016, Darrell Issa’s seat was rated “Safely Republican” by the Cook Political Report heading into the primary. But he ended up claiming just 50.8 percent of the vote, the closest House election of the cycle.
If this is a wave environment like in 2006 or 2010, which would probably make the Democrats slight to modest favorites to retake the House, it should not be too hard to tell. (Read more here.)

Here are the districts that are coveted by Democrats.
Democrats think they have the best chance to flip these districts, which Mrs. Clinton won in 2016. But it is an open question what the presidential result may mean for Democrats in the midterms. Check out more about these districts here.
