When the VFW/VFW-PAC endorsement monster reared it ugly head it was Milbloggers and some other notable sources that drove the issue.
TAH has a proper overview of the current status here. A somewhat harsher take can be found by Mr. Wolf at Blackfive. I should mention a well reason post by Mothax at The Burnpit, as well as Ed Morrissey over at Hot Air, and David Bellavia over at his place.
Personally, I think burning our membership cards is over-the-top, but either way those folks doing the heavy lifting and keeping the VFW’s feet to the fire on this issue deserve the thanks of VFW members (at least!) everywhere.
