Daybreak tracking poll, which was different from other polls as it had Donald Trump in the lead more often than not. The poll's findings caused skepticism, especially from other pollsters and media outlets, who have denounced it and often criticized the LA Times for running it. Before the election, Nate Silver deemed as positive the fact that the poll allowed people to assign themselves a probability of voting for either candidate instead of saying they're 100 percent sure, saying if people are "going to browbeat a pollster, et'sdo it to a pollster who is doing things cheaply—some of the robopolls qualify—and not one that’s trying to move the ball forward, like the LA Times poll." The LA Times concluded after the preliminary results of the election were published: "That doesn't necessarily mean that a poll conducted online, the way the Daybreak poll is, necessarily will be more accurate than polls conducted by phone. But it is yet another indication that polling needs more, diverse ways to look at public opinion, not fewer."
