Naturally, Suffolk drops that really good Harris +3 poll in PA and Insider Advantage counters with Trump +2
Even RCP thinks Insider Advantage sucks ass - in 2020, they were 2.4 off the final margin, 67% error rate that favored Republicans. They were worse in 2022 - 5.8 off the final margin and 81% error rate in favor of the GOP. Only Trafalgar (86%) and Rasmussen (100%) were worse.
So when you see polls, they generally fall into these categories:
GOP-lean or outright GOP partisans: Insider Advantage, Trafalgar, Rasmussen, Remington, SOCAL, Patriot Polling, Cygnal, Fabrizio (Trump's campaign pollster), McLaughlin
DEM-lean or outright DEM partisans: PPP, GQR, D4P, GSG
Mainstream: Suffolk, Marist, Monmouth, Siena, Quinnipiac, Morning Consult, Bloomberg, YouGov, SSRS (CNN), Beacon / Shaw & Company (Fox News)
