He is indeed the next Cindy Sheehan.
Someone the Dems will try and use to tug at people's heartstrings to build support for the Dems' policies. Then, when he/ she gets too big for his/ her britches and turns against the Dems (i.e. Sheehan running for Pelosi's seat some years ago, and now Hogg talking smack about her and other Dems), they'll drop him/ her in a heartbeat and allow him/ her to fade into obscurity.
