I think this is waaaay too friendly for the Trumpster but South Dakota is anyway safe R.
The South Dakota two-party Democratic (Obama) percentage was 40.8% in 2012. Here, in my weighted numbers, it's 39.8%. So, assuming a uniform swing (a big assumption that's likely not true), this poll says we're more or less on par with 2012 election results nationwide - or at least in South Dakota. That result is pretty much is in line with the national two-way polling average right now, too.
This election is more like 2008 than 2012.
