All votes carry equal weight, so, based on her votes, she's the 3rd (or whatever) most liberal Senator in Congress. Unfortunately, Bernie is not challenging this idiotic argument.

All votes are NOT equal, and this is what Bernie should do, because Americans need to be reminded about the consequences of this 1 vote. Rather than merely mentioning that Hillary voted for the war, he could filibuster for 5 minutes:

First, Hillary was told by Bush 41 that it would be idiotic to remove Saddam because he's the only thing holding the ME together.
Second, she naively trusted BushCo.
Third, X thousand Americans have been killed
Fourth, X hundred thousand Americans have been maimed physically and psychologically, lives and homes destroyed
Fifth, hundreds of thousands of innocent Iraqis have been killed and displaced
Sixth, just as Bush 41 cautioned, removing Saddam destabilized the ME
Seventh, we've now spent $X trillion on the war
Eighth, we're now in a perpetual war
Ninth, trillions and trillions of dollars will continue to flow to the ME as a result, money we should be spending here
Tenth, it created ISIS

No, I do not accept that this was "just 1 vote." When you unravel it as I have done, you can understand it as a series of neocon votes. No one who made this vote should be rated as "liberal."

This is why I insist Bernie is giving Hillary a pass. He can destroy her on both of her idiotic wars and the (news to me) dog whistle language and policies from the past.
