There are 20 women in the US Senate, with 14 of them being Democrats, and 6 being Republicans.
News has emerged that 13 of the 14 women Democratic Senators are about to endorse Hillary Clinton for President.
The exception is Massachusetts Senator Elizabeth Warren.
Warren is seen as much more to the left on many issues than Hillary Clinton, really much closer in views and attitudes to Independent Socialist Senator Bernie Sanders, who is also running for President, but not gaining any significant support from fellow Senators.
The question is whether Warren will endorse Sanders, who is still seen as a long shot for the Democratic Presidential nomination.
Warren is keeping her options open, but at the end, she will endorse Hillary when it is clear that Sanders cannot win the nomination.
Until then, Warren is effectively making Hillary Clinton squirm!
