Insert snarky comment about your lack of spelling errors here. (Oops, wait, you forgot the 's' at the end of 'racists' in the third one...)
Of the ones you listed, the first one's the best. I don't think any of them are really angry enough for a Tea Party sign though. Something more like:

or maybe, if you wanted to be a little more subtle about it:
Deficits Are Color Blind!, with a nice multi-racial picture of all the different people who'll be affected (i.e. everyone) if the debt and deficit don't get dealt with.
