Not only is 60 the number (not 55) but you forget the RINO factor..
The RINOs are not "moderate Republicans". They are socialists.
Lincoln Chafee? You honestly count him as a "Republican"?
The liberals control the Senate. The Republicans control the battle of the "letter"--"R" is bigger than "D".
But face this fact. The LIBERALS control the Senate. The Democrats + Jeffords + the Chafee type Marxists in the Republican Party gives the Senate majority to the liberals.
"Red Nation" is rising, but damn, that almost sounds like something Gus Hall might have applauded.
