I'm not able to make the time to do the digging I'd like to at the moment, but playing around with the R-I interface that allows users to toggle cross-tabs, I noticed that since September 1st, R-I has sampled just 376 likely voters in Texas to 565 likely voters in Virginia. The 50 states and DC add up to the entire nationwide sample so there isn't any weighting of responses taking place as R-I gets to its national polling numbers.
Given that Texans cast more than twice as many votes in the 2012 presidential election as Virginians did, that's a bit... odd. And given that Texas is a red state while Virginia is a blueish-purple one, maybe it's actually more Oddjob than just odd. There's more than a little evidence that the deck is being stacked.
