at thanksgiving, many of us will be subject to <u+2014> or subjecting our hosts to <u+2014> a wide range of opinions about the 2016 election. but some aspects of it are rooted in fact <u+2014> not open to interpretation (sorry, uncle bill). below, we present a compendium of sorts about the election, to help guide you in your discussions. some of these may seem basic, but they are by no means obvious to everyone. don<u+2019>t let them get in the way of a good holiday argument. hillary clinton definitely won the popular vote, and that lead is only going to grow. the new york times called the election for donald j. trump at about 2:40 a.m. on nov. 9. at that time, he had about 57.2 million votes, almost a million more than hillary clinton. even before then , the signs pointed to her edge in the national popular vote. most of the votes that remain uncounted are in heavily democratic places like california. even roughly two weeks later, the state estimated that it had about two million ballots yet to be counted, including about 760,000 in los angeles county, where voters have preferred mrs. clinton by around 50 percentage points . as the votes have trickled in, the popular vote has tilted toward mrs. clinton. as of wednesday morning, that lead surpassed two million votes, or 1.5 percentage points better than mr. trump. (our time-stamped estimates are courtesy of dave wasserman <u+2019>s excellent popular vote tracker .) this lead is still growing, but it<u+2019>s already a larger margin than in popular vote victories by al gore in 2000 , richard nixon in 1968 and john f. kennedy in 1960 . turnout in the 2016 election was not low. it is about the same as it was in 2012 and comparable to most 20th-century presidential elections. turnout is simple to calculate: take the total number of votes cast and divide it by the total number of adults who are eligible to vote, and presto, you have a turnout rate! when the race was called, this math problem yielded a rate that was , indeed, historically low. it was also wrong, for the same reason mrs. clinton trailed in the popular vote at that time: not all the ballots had been counted. because the denominator in this math problem <u+2014> the number of voting-eligible adults on election day <u+2014> does not change, the turnout rate goes up every time ballots are counted. as they have come in, the turnout rate has risen to about 57.7 percent. michael mcdonald at the united states elections project estimates that it will ultimately be closer to 58.4 percent, a bit lower than it was in 2012 and roughly comparable to most presidential elections in the last 100 years. yes, the polls were off, but not in extraordinary ways. mrs. clinton held a modest but steady lead in nearly every national poll for months, and led most state polls in florida, north carolina, pennsylvania, michigan and wisconsin. yet she lost in each of these states. so how wrong were the polls? on average, by about 3.4 percentage points in the closest states. that<u+2019>s higher than in any election in decades, but comparable to polling misses in 1988 and 1992. the 2016 polling miss feels much larger because the places where mrs. clinton fared worse than polls suggested were concentrated in a few battleground states. the places where she fared better than expected were in big liberal states, where she had almost no chance of losing. nationally, these effects nearly canceled out, which is why her national polling lead before the election <u+2014> t hree to four points <u+2014> ended up being close to the result (which, again, is about a 1.5-point lead and is expected to grow as more votes come in). third-party candidates, like gary johnson and jill stein, may have cost mrs. clinton michigan, but they almost certainly did not cost her the presidency. the total vote tally says about 4 percent of all voters, about 5.8 million people, voted for mr. johnson (3.3 percent) or ms. stein (1 percent). in four battleground states that mrs. clinton lost <u+2014> florida , pennsylvania , wisconsin and michigan <u+2014> the votes for these third-party candidates exceeded mr. trump<u+2019>s margin of victory. if those states had flipped, mrs. clinton would be president. are third-party voters responsible for the trump presidency? almost certainly not. with the exception of michigan, third-party voters would have had to overwhelmingly favor mrs. clinton to flip the state. that notion also rests on a significant number of third-party voters coming to the polls, but many of them told pollsters that they would have stayed home if they could not have voted for their third-party candidate. if we look at mr. trump<u+2019>s margin of victory in these four states and the number of votes cast for mr. johnson or ms. stein, we<u+2019>re left with a simple math problem: if those candidates did not exist, what share of those votes would mrs. clinton have needed to pick up to overtake mr. trump<u+2019>s vote lead? the answer: a substantial share. might these voters really have preferred mrs. clinton to mr. trump to this degree and showed up to the polls at higher rates than they told pollsters they would? it<u+2019>s possible. but for that vote to be decisive, pennsylvania or florida and at least one other state would have had to flip. the evidence we have suggests such an outcome would have been highly unlikely; if anything, the johnson vote could have easily leaned toward mr. trump. exit polls are useful, but don<u+2019>t give them too much credence. as my colleague nate cohn has written , exit polls are helpful, but using them to come to conclusions about the precise composition of the electorate is risky <u+2014> and frequently wrong. in 2012, they painted a picture of the electorate that was younger and more diverse than it really was. many important questions remain about precisely who voted, and why. did poor democratic turnout doom mrs. clinton, or were swing voters the key to mr. trump<u+2019>s win? did mr. trump really do better among hispanic voters than mitt romney? further analysis of the voter files <u+2014> which show who voted and who didn<u+2019>t <u+2014> will provide more clarity in the months ahead. exit polls alone are not a definitive way to answer these questions. but a few things, as we<u+2019>ve tried to explain, should be beyond debate, as should the idea that thanksgiving dinner ought to include at least some time not devoted to politics. the upshot provides news, analysis and graphics about politics, policy and everyday life. follow us on facebook and twitter . sign up for our newsletter. a version of this article appears in print on november 24, 2016, on page a3 of the new york edition with the headline: handy election facts for holiday discussion. order reprints | today's paper | subscribe
