hmm, how does PPP compare to Strategic National and Trafalgar?
PPP's personal leanings are Democratic (they are open about this), but historically their polling has been quite good, and they have a long track record. Several years ago they showed a D-lean in their polling, but this has disappeared in recent years. At present, 538's pollster ratings gives them a B+ with a bias of R+0.2, based on 383 polls, of which they've called 82% correctly.
Also, their Twitter feed (
https://twitter.com/ppppolls/) is usually amusing.
EDIT: I'm sure you already knew that, Senator, but I posted it anyway for the less informed.
