Recently become a net exporter of all petroleum products, with Texas, North Dakota, New Mexico, Oklahoma, Colorado, Alaska and California being the largest producers. At least in the near term I don't think the flyover states are as reliant on imports as the coasts if you were to put them in separate categories.

Pretty sure if there was such a split, gulf coast states and their ports would go with the inland farmers. So petroleum would be imported around the Mississippi. Likely a split would have the ‘red’ states net exporting petroleum.

Don't forget the massive subsidies to corn farming etc. generated by Federal mandates for biofuels.
