Romney won Arkansas in 2012 by about the same margin Obama won Maryland. Just for perspective.
Yeah, but Arkansas is very fond of the Clintons, most voters there are registered Democrats, and President Obama is very deeply hated up there.
Still, imagine a poll showing a certain Republican leading generic D by 2 points in Maryland. When I look at it from that perspective, it's easy to see why the Republicans are in desperation mode trying to bring Hillary down.
A poll showing a generic R up by 2% in Maryland would indicate that the recent D coalition for victory is in trouble and that the Democratic nominee needs a new coalition to win the next Presidential election. The Democratic nominee would have a chance to lose anywhere between 42 and 48 states and get somewhere between 10 and 119 electoral votes. The reason for such a broad range of bad results is that two of the states on the margin would be California and New York. Coalitions can collapse; look at the Carter coalition between 1976 and 1980 or the Hoover coalition between 1928 and 1932.
Arkansas is not 'near' any giant states in electoral votes that would travel with it. Maryland is just blandly and unselectively liberal. Arkansas is less like Texas in its politics than Maryland is like California. The only 'somewhat similar' state in politics to Arkansas with more than ten electoral votes is Georgia. It has had its swings between populism and conservatism. Most of the states that more heavily voted for Romney in 2012 and some that less heavily voted for him in 2012 are 'conservative' for very different reasons.
So what if the Democratic nominee for President were a Mormon who won the blessing of the LDS hierarchy and had a 6% lead in Utah despite being a liberal because he lives a model life for a Mormon? What would that say of any trend outside of Utah? Practically nothing. Such states as Alabama, Nebraska, and Texas are politically conservative for reasons irrelevant to Utah. Did I tell you that the nominee's parents are Samoan? The ten electoral votes of Idaho and Utah are still not enough for the Democrats if they are losing Colorado, Florida, Iowa, New Hampshire, North Carolina, Ohio, and one of Pennsylvania and Virginia.
As it is, the Democrats show no sign of a collapse of the current coalition of victory, and states like Arkansas, Kentucky, and Louisiana are added layers of icing on a cake.
