It's possible, but not likely. I am sure Q will poll its home state at some point.
Roll your eyes at me all you want, but the last Q poll from June had it at -7/-5, which puts CT in "Lean D" territory. A win for Trump in that scenario is possible, but unlikely unless there's a uniform shift towards Trump.
Plus, if you have all of this movement towards Hillary in states like Texas and South Carolina, as you red avatars claim, and the national numbers basically are at Obama 2012 territory, where does the other Trump vote logically come from? The Northeast where there are a lot of blue collar Catholics.
While Connecticut is an unlikely get, it's not an impossible one for the Trump campaign. There's a difference. The question posed by the OP was can Trump win CT, not will he. Can he win it? Sure in a perfect storm scenario. Will he win it? Probably not.
...You actually think CT is lean D?
I don't think when it comes to ratings like that. I look at data.
The RCP Average is +7.5 (2-way)/+5 (4-way) academically, that makes it lean D.
Lean D is a Democrat lead between 5 and 10 points. Obviously, we need new data points.
As I have stated numerous times on this thread the question is whether Trump can win Connecticut. He can. There is a path to victory. However, it's unlikely that he wins the state. That's a distinction with a difference.
What is Trump's path of victory in CT?? He really has none. Trump's base is white working class voters without a college education. That base really doesn't exist in CT, especially where the people are. 4th highest bachelor's degree % in the nation, 3rd highest advanced degrees.
