Are Most Public Polls Garbage?

David Plouffe talks to Greg Sargent about the tightening polls:

“Some polls closely capture where the race stands. But they’re very incomplete. The Clinton campaign is doing large samples for modeling surveys of everybody on the voter file. So you have a very good understanding of how you believe 100 percent of the electorate will be allocated on election day.”

“When you look at how 100 percent of the vote is likely to be allocated in Florida, I get very optimistic… I can get Donald Trump to within two or three in Pennsylvania, but I can’t get him to a win number. The same is true in Virginia and Colorado. I know everybody goes crazy about the latest Cheetos poll, but I feel very confident about both New Hampshire and Florida. So that puts her over 300 [in the electoral college]. Trump has to pull off a miracle in the electoral college.”

Jim Messina said pretty much the same thing on Political Wire Conversations last week.
