Gabbard is not my first choice for the nominee (she’s not in my top three), but the idea that she’s a Republican is overstating things. On almost every issue, she fits into the progressive wing of the party.
There are two, perhaps three exceptions. The first is Syria, where her position more or less matches Trump’s (get us out, leave Assad in power). Syria is not simple. It’s not the Bad Guys (Assad/ Russia) vs the Good Guys (Kurds and… ?). It’s a clusterfuck with very bad actors everywhere, and only a handful of those we would normally support. I disagree with her position, but I respect that her service in Iraq gives her a different perspective.
The other is LGBT issues. She changed her stance in 2012. Before that, she was against gay marriage. Is she sincere? I have no idea. If you’re looking for a crusader on LGBT rights, she’s not it. But she’s also not Mike Pence. At a bare minimum, I assume she can be trusted to follow along with the party on this, even if she does so grudgingly in her heart of hearts.
She’s been accused of being an Islamaphobe, partly because her views on radical islam are similar to Bill Maher’s. Her family also has ties to a very conservative party in India. But again, she’s not in the red-hat “put them in camps” crowd.
From an identity standpoint, she’s a young (37) woman of color who actually served in the armed forces. She’s also a pretty good speaker, and I suspect she’ll do well in the debates.
If LGBT issues are a top priority, I can understand why you’d distrust and dislike her. If you are firm that we should stay in Syria to topple Assad (and replace him with… who?), it also makes sense to oppose her. Speaking as someone mostly concerned with healthcare, climate change and voting rights, however, her positions look pretty reasonable at this stage. I’m sure we’ll learn more later.
I’d rather see Klobuchar, Gillibrand or Beto in the top spot. But Gabbard is not a republican ;)
