What policy positions does Tulsi have which would make Democrats unable to support her?
Incredible war hawk.
Supports universal healthcare, is anti-TPP, wants to toughen up on Wall Street and so on.
In other words, she's the antithesis of everything the Booker crowd wants.
Sure, there are areas to disagree with her on, but at least make it genuine. She's not an over-the-top war hawk. Heck, Obama's got what, 7 wars going on now? Plus, she's said herself she wants to put an end to wars of regime change, something Hillary has voted for in the past.
At least make your disagreements with her genuine instead of lining up fake attacks.
Adopting rhetoric on Islam and terrorism that's aligned with the Breitbart crowd, even to the right of the Bush administration, isn't disqualifying to the so-called "progressives"? Aligning yourself with the RT/Breitbart/Putin/Assad/Trump side on Middle East matters isn't disqualifying to the so-called "progressives"? Sorry, but I'll take a Wall Street backed Corey Booker over this Russophile Islamophobe any day.
Why? Economic policy matters in everyday life. Booker would harm more people than Gabbard.
