For those who doubt or may have forgotten the difference between Registered Voter and Likely Voter polling for some polls, here’s a chart of every CNN/Opinion Research Generic Ballot poll from 2010, showing Republican lead or deficit per poll, with the RV and LV polls separated.
Clear difference, I’d say.
By request, I’ve decided to take a look at just what kind of electorate the Public Policy Polling screening of Likely Voters seems to be predicting. To do this I will use recent PPP polls from two states: California, which went for Barack Obama heavily, and West Virginia, where Obama’s popularity has never been that hot.
A website called The Conservative Journal is releasing polls now, with an archive available on the website.
The polls are definitely making the rounds on the right, thanks to results that are relatively good for Republicans. But are they worth the pixels they’re printed on? It’s hard to say.
It’s October. The baseball games start to count for more, and in the National League where men are men, and players play on the field, the games become riveting managerial duels. Yes, I know I just lost readers. My Dodgers are home now and I can say what I want.
The polling is also getting more exciting though, as even the Gallup Poll is moving to a Likely Voter model. Let’s see where we are versus last week’s 49 seat Republican gain.
So Newsweek put out a new Generic Ballot. The magazine’s polling had drawn notice before in my House projection reports (this week’s edition coming later today), but this new one just seems completely out of line: Democrats +5 among Registered Voters. That filtering is expected to lean to the left after the 2008 anomaly, but this is ridiculous.
Scientific polling, based on the laws of probability and the compounding of likelihoods, is a mathematical activity. It’s all about the numbers. Without the numbers no poll has meaning. That’s why I highlight key facts like Margins of Error.
Your typical internal poll release is very low on numbers and instead is a one page memo. Those releases can be based on sound polling practices, but they are firstly designed to push an agenda. When I see this new Illinois poll, I am reminded of an internal poll release.
This new poll of the California races by Greenberg Quinlan Rosner and American Viewpoint for USC and the LA Times has been discussed from one side of the Internet to the other, and back again.
But I wouldn’t be doing my job if I let it go without chiming in, now would I? Of course not. So let’s dig in.
Carly Fiorina trailed the Republican primary most of the way after Tom Campbell entered. But in the end she got the right endorsements and spent the money it took to get her message out and win.
She’s now going on the air against Democrat Barbara Boxer, a move I think is important because her deficit in SurveyUSA’s new poll is a bit larger than I think it needs to be for her to hang around and win in the end.
