[Ooh-Ah]

I cannot find anything from PPP showing if the survey was of:

Registered Republicans
Likely voters
Or, WHAT?

They only say this in their press release:

PPP surveyed 404 Republican primary between February 10th and 12th. The margin of error for the survey is +/-4.9%. This poll was not paid for or authorized by any campaign or political organization. PPP surveys are conducted through automated telephone interviews. PPP is a Democratic polling company, but polling expert Nate Silver of the New York Times found that its surveys in 2010 actually exhibited a slight bias toward Republican candidates.

Can anyone interpret this???

Can anyone interpret this???

Polling groups are biased, but usually try to be accurate and professional (outside of push polls or released internals).

PPP and EPIC/MRA lean dem.
ARG and Mitchell lean Republican.
I've seen Mitchell give better dem numbers than EPIC/MRA.

BTW - here's the crosstabs

70% GOP
26% Indy
4% Democrat

BTW - There are no registered parties in Michigan. Anyone can call themselves anything they want.

I suspect from their terse description their sample consisted of people called at random who said they are registered voters and were intending to vote in the MI GOP primary. Unlikely that they did any further cuts or verification questions.
