This is just more of Trump's "truth to power" schtick he riding. Its backfiring because even though its sort-of true, it's also a step too far. All vets (except Chelsea Manning and Bowe Bergdhal) are Heroes(tm) because they are vets. Challenging our civic religion is still forbidden, it seems.
Those two are still more heroic than most Americans. At least they were soldiers at one point. You're just upset that Chris Kyle can't run for Senator from Tejas to replace Cornyn, you must be devastated.That was supposed to be sarcasm, indicated by the (tm). (Sometimes this site really could use some emoticons.) I was trying to touch on the Orwell-like hypocrisy about how the Right considers that all members of the military are somehow heroes (no matter what they actually did: good, bad, or nothing ) except when they do something the Right doesn't like. Then their "soldiers are all heroes" line somehow evaporates like morning dew. Politically, I'm very far left, and a supporter of Manning and Bergdhal (and Snowden, Assange, Bryant and many more).
I do think it would have been funny to watch Cornyn get primaried, though. Not that it would change anything.
