Susan Colins, is and has always been a RINO. All you have to do is go to Senate.gov and do a search how she voted and you will find that she voted mostly with the rats, except in 2012 when she ran for reelection. John McCain and Lindsey vote mostly with the other Republicans, which clearly do not make them RINOs
Did I use the term 'RINO'? No.
The point is, especially with respect to McCain & Graham, is, look at some of the anti-conservative issues that have their support, like ' comprehensive immigration reform' and feelgood, squishy statements about how nice a guy Obama is. Who cares if they vote with the other Republicans, if the other Republicans are only half a chromosome from being a liberal?
McPain and “Loveable Lindsey” are RINOs by temperament if not by some rigged voting record tally.
