I'm not sure what point you are trying to make. You think the government doesn't have or can't aquire food/fuel supplies? You think they can't wipe out the bread basket states' ability to produce food for the rebellion? Cut off most supplies to the citizens? I'm not buying it.
I'm saying if you cut off access to a military base of any variety then said base is living on borrowed time. Nevermind that if numerous states rebel supply lines could be cut at any place at any time. Once again, look at Afghanistan. There are supply problems there and those supplies comes from a single, large supply line protected by the combined might of the US military, stretched over a relatively short distance (compared to the distances in the continental US).
Securing and supplying the myriad military bases across the continental US would require securing a ridiculously high number of supply lines of greatly varying lengths from a (presumably) determined adversary. Can you say "logistical impossibility"? Imagine if in Afghanistan right now, you fragmented our single supply line through Pakistan into hundreds and routed many of them through the most hostile provinces of Pakistan. Yeah, good luck with that.
This isn't the USSR, food and supplies don't go through some governmental distribution network they can just shut down on a whim. Short of destroying farms, which would be tough going considering likely military defections, what are they going to do?
I'm not saying it would be an easy or simple thing, but it's definitely plausible. If you don't want to buy logistical and military realities, that's your problem. I've had similar discussions with multiple members of the military and they all agree with my general premise. *shrug*
