Clinton Regains Lead in Dubious LA Times/USC Daybreak Poll

5. I think the reason the Rand poll was correct in 2012

is because it had a sample that was representative of the country. The problem with a tracking poll like the LA Times/USC poll is the sample of 3,00 is locked for the duration of the election. If they over or under sampled any group then they are going to be off badly and I suspect they did. Even they say their poll isn't going to have as much movement as other polls. Hard to get a real detailed break down of their internals,but some things were interesting. Among the 18-34 old demographic Clinton leads 51 to 41. There is no way Trump is within 10 points of that demographic. Also even among people who said they planned to vote for Trump don't believe he is going to win. I think they probably over sampled republicans.
