Why did she vote present instead of no? If she had real scruples she would have voted no. But, she can not offend the far left wing base of her party.
In reality she is positioning herself for a presidential run in 4 plus years after Trumps reelection. She knows full well this election will be a disaster for the democrat party. She hopes to pick up the pieces of this disaster and become the next candidate. She may succeed. For her to succeed she must divorce herself from the left. However, she has made many policy statements that are extreme left.
I really do not know what she really is. Obama ran as a moderate and once elected became an extreme leftist.
What is Tulsi Gabbard really? We do not know.
