Streisand gave a speech of praise on why she has chosen to endorse Hillary as opposed to the others:
"Hillary is a powerful voice for change as we find our country at an important crossroads. Under her leadership, our country will regain its respect within the global community. She will prioritize issues of global climate change, universal health care and rebuilding a strong economy. After eight long years, the public will once again have faith in their government."
I couldn't have said it better myself. She realizes that America is going through tough times, and we are desperately seeking someone who can give us all hope once again and carry us into 8 years of prosperity. You can either be oblivious to the problems America faces, or you can get involved and make history. Barbara Streisand is the true definition of a patriot.
