Rick Santorum argument for that poll is that it would apply to WI and MN as well considering they're neighbors. I don't believe that, I think its a sampling error.
He's not 100% wrong. For instance when Ohio was tightening, MI and WI were moving farther from Trump. Some have argued Ohio is moving towards Trump now and thus MI and WI would move towards him a bit...but the last Ohio polls we saw were good for Biden.
The thing I'm looking at are district polls and state polls. In 2016, Wasserman hit the alarm about Hillary collapsing in the district polling. This year? Biden is well ahead in district polling in PA and MI for instance. I feel great about MI, and feel good about PA. We will see.
If Trump wins sure, I'm sure some will point to the Iowa poll as a harbinger. But it should also be pointed out that it was virtually the only thing to point to. Everything else looked good/great for Biden except that poll. So I'm not freaking out.
I just want this to be over with.
