The turnout was healthy — after all, most people vote absentee, and more people voted than in 2008. Clinton won by a big margin. It’s not plausible to suggest that Sanders lost anywhere near that kind of support thanks to long lines. The math just doesn’t work, given how high the turnout was and Sanders’s small four-point edge among Election Day voters.

Toni One electoral oddity our readers may not know about involves California. A lot of would-be Sanders supporters mistakenly registered with the American Independent Party. They were misled by the word “independent” in the party’s name. It turns out it’s a party whose “platform opposes abortion rights and same-sex marriage, and calls for building a fence along the entire United States border.”

Nate I don’t think many Sanders voters are hurt by the American Independent Party. Less than 3 percent of registered voters in California are members of the A.I.P., and around half are probably Republican-leaning independents, not Democratic-leaners. Of course, it’s not as if Sanders would win all of these voters. And the turnout among non-Democratic voters is always lower as well. I think it’s hard to argue this hurts him by even one percentage point.

Toni Clinton has been ahead in the polls in California. But will we get another Field poll before the election? Can you give a brief explanation of why the Field poll is so highly regarded?

Nate I don’t know whether we’ll get another Field poll, but I hope we do. It’s just one of the best polls out there: It has a long track record; it’s conducted off the state’s voter registration file (which is important generally but even more for a semi-closed primary); it’s a big sample; it’s calling enough cellphones. It checks all of the boxes.

Toni Amy Walter of the Cook Political Report wrote: “This year, the electorate will be divided along race, education/class and gender like never before. I’m preparing myself for a campaign that is going to be nasty and ugly and will leave the country more polarized than it is today. There’s nothing to be happy about there.” This truly is going to be an election of demographic division, isn’t it?

Nate If Clinton wins this election, I’m not sure whether it will involve a much greater racial divide than in 2012. But it probably will be more divided by education, at least among whites, and gender.
