Good news! If Trump underperforming in laaaarge Texas and Utah, but Hillary is still just 3% ahead, he is overperforming in the blue states!!!!!!! 
Well, she's generally only up in the teens in NY and CA while Obama won them by 25-30. Also, TX has extremely low turnout. Total votes cast were on par with NY in 2012 even though NY has 9 fewer CDs and was hit by a hurricane the weekend before the election. If TX is closer because a ton of dormant Dems are turning out and some dormant Trumpy indies as well, that won't skew the national results as much.
I was kind of joking, but not really
You should compare polls to polls.
Hillary is definitely not doing worse than Obama i CA, likely better (may be by a lot >5%).

NY, probably you are right, but it wasn't much polling there, actually. I'd wait until Siena's poll. She's probably doing slightly worse than Obama. (
%)
So she is in general doing better in non-swing states. In polls, at least. Don't either forget that ~50% of hispanics live in CA/TX. That might "skew" nationall polls as well.
And BTH, right now I'd only be looking into nationall polls and states that was recently polled by at least >3 A/B pollsters. Othervise, you might get some surprises, when we'll have got more good polls :-P
