What is a "Republican poll"?
My guess is that he trusts Rasmussen because they are generally pretty accurate in their polling (for however accurate polling can be to begin with). Most so-called pollsters aren't even pollsters; they are Democrat Party public opinion manipulators.
False.
Meh. Basically all of the major "polls" that cycle were missing in favor of Romney.
Rasmussen - Romney +1
Gallup - Romney +1
Politico - TIE
CNN - TIE
Monmouth - TIE
IBD/TIPP - Obama +1
NBC/Wall St - Obama +1
Notice how those "polls" are all within 2 points of each other?
Now, if you want to look at some TRULY embarrassing stuff, look no further than the Wash Post/ABC poll for Wisconsin in 2020... Biden +17?!?!?!?
If you follow along with "polls", you'd also notice that the Democrat Party public opinion manipulation "polls" (read: press releases) will always skew very heavily in favor of the Democrat candidate during the summer leading up to the (s)election, and then they will always "herd" (or "narrow") right before the (s)election. That's how you can tell Democrat Party press releases from actual pollsters. Pollsters results won't change much over the summer and leading into November, but the Democrat Party press releases will always have such drastic changes between their summer press releases and their November (or late October if they are too cowardly) press release.
For instance, in this last cycle, NBC News seriously released a Harris +6 poll before herding at the end. HarrisX had Harris +5. Economist/YouGov had Harris +4. NYT/Siena had Harris +3 before herding at the end. Oh, for another LOL "poll"... Ann Selzer had Harris +3 in IOWA

She "missed" (it was purposeful) by SIXTEEN POINTS.
