None of which are at all relevant if the same capabilities are available to the same orbit out of the Cape.

I'm a big fan of saving taxpayer money and a big fan of SpaceX. However, convincing me that the USAF should maintain multiple launch sites with these capabilities is not a difficult task.

I suggest you continue in this line-of-thought. What would be the ramifications if FH performance is so good that doglegging makes a presence at Vandy pretty much pointless?I suggest you look further than just 'No Vandy'.

It's the USAF that would have to justify to Congress why NSS launches should abandon VAFB. You know, 'calling into question the existence of a vital military base' and whatnot. Perhaps we're both right – let's call it two sides of the same (Federal) coin.It may well be the polar launches migrate to the Cape, in time. But one reason Vandy is currently specified in the Phase 2 RFP is to avoid the political shitestorm which would result if it wasn't.
Legacy launch providers (Delta, Atlas Centaur) have long had to deal with the relatively low orbital launch rate to polar orbits from there. I believe that most have often ended up with skeleton crews that are augmented with East Coast people for launches. SpaceX will likely do the same, now that Iridium Next is up. - Ed Kyle

That is a fact. I also know that SpaceX has been actively brainstorming over what to do with their presence at Vandy during prolonged low flight-rate periods. One of the ideas that surfaced from those brainstorming sessions was to get out of Vandy completely. Courtesy of the recent dog-leg corridor being opened up at KSC. They worked out that basic idea a little further to see what other cost-savings could be achieved by abandoning VABF. I'm curious as to how much the folks here would be able to come up with similar results, simply by thinking the idea thru. So far I've seen none.
Thinking on it, all i could get was- they could move the ASDS over to east coast and perhaps not need to build a 3rd- lose the inefficiency of sending stuff east to Texas and then back west.
I also thought maybe they could transfer some of the GSE from Vandy to Boca to jump-start its use for F9, but it wasn't obvious that the GSE could actually be moved. Can you ship a TE and supercooling facilities across the country?

VAFB is absolutely necessary for missile test launches, etc. Legacy launch providers (Delta, Atlas Centaur) have long had to deal with the relatively low orbital launch rate to polar orbits from there. I believe that most have often ended up with skeleton crews that are augmented with East Coast people for launches. SpaceX will likely do the same, now that Iridium Next is up. Maybe polar orbit is possible from the Cape (it has after all been done before; but Cuba, remember), but there will still be orbits (retrograde) that cannot be reached from Florida. No way will the Pentagon let that capability go, IMO. - Ed Kyle
