I find it very hard to believe that Clinton is underperforming in the traditional democratic states. But we will see when we get more data
Well, underperforming in the sense of trend, not necessarily swing. I mean, let's looks at what we have so far. We've seen that Christie vs. Clinton produces some weird results, though PPP isn't polling Christie anymore. They're still polling Clinton vs. Rubio though. Here's the margin in all of PPP's polls of Clinton vs. Rubio since Jan. 1:
national, Jan. 3-6: Clinton +14
Florida, Jan. 11-13: Clinton +4
Minnesota, Jan. 18-20: Clinton +13
Texas, Jan. 24-27: Clinton +1
national, Jan. 31-Feb. 3: Clinton +8
Alaska, Feb. 4-5: Clinton +1
Louisiana, Feb. 8-12: Clinton +3
Georgia, Feb. 15-18: Clinton +3
If you assume that the true national margin is the Clinton by 8 seen in that Jan. 31-Feb. 3 poll, then relative to the 2012 election, the trend would be:
Florida: R+1 (Rubio's home state)
Minnesota: D+1
Texas: D+12
Alaska: D+11
Louisiana: D+16
Georgia: D+7
But, OK, maybe, as you say, the true national popular vote margin is larger than that. Perhaps something more like the 14 point margin from the early January poll. In that case, move each of those trend numbers a few points towards the Republicans. You still have a decent Democratic trend in at least Texas, Alaska, and Louisiana. That *has* to be made up somewhere. That's the nature of trend. It all has to balance out. Minnesota, then would have a bit of a Republican trend. I'm just suggesting, maybe there's a bit of a Republican trend many other Democratic leaning states as well. Not sure, just a thought.
