Different battles. The one (Brown) was to kill the socialist care debacle. This one is the clean the RINOs...!
Different battles, yes. But getting rid of McCain would remove a huge amnesty advocate and overall give the GOP a solid conservative vote in JD.
When Brown says RomneyCare is good, but ObamaCare is bad, my liberal alarm goes off and so should yours.
IMO, trading McCain for Brown gets us an even bigger Rino.
