I'm reluctant to link to them because they were all Drudge Report style aggregators of the type that are frowned upon by HN. Anyone curious can just Google "Romney win riots" and see for themselves. We're talking hundreds or thousands of tweets of this nature.
To be honest, I'm not really bothered by either because it really just amounts to verbal graffiti. I don't think any of those tweeting were future black panther revolutionaries, any more than I think the ones featured in this post were future James Earl Rays. They're all just lacking empathy, common sense, and inhibition on Twitter.
