This isn't a Republican forum: it's a Conservative one. What's the point of voting for Lincon Chafee, Olympia Snowe or John McCain? It doesn't advance conservatism: it just advances liberalism a little less quickly.
The true RINOs are those who don't vote "R"
The point of voting for McCain is he isn't Obama, isn't going to raise taxes in the middle of a recession, is a hawk not a dove, and won't roll over to let Iran get nuclear weapons. Chafee and Snowe have precisely nothing to do with any of it.
And if you don't care what is republican, I suggest you get a new slogan besides "RINO". Personally I say centrist squish, I find it far more descriptive, also it is accurate. Whereas RINO isn't - see above in re pretenders who don't actually vote republican.
