Things I like: Non-interventionist foreign policy, endorsed Bernie in 2016, she once tweeted Trump saying "being Saudi Arabia's bitch is not 'America First'" which was fun. Has spoken out against the genocide in Yemen. Supports making community college tuition free while making all four-year colleges tuition free for students with an annual family income of $125,000 or less. $15 minimum wage. Her bad past record on LGBT/abortion seems to have really changed-she grew up in a very conservative family and she said that influenced her views when younger. OFF Act is a decent piece of legislation (seeks to ban fracking).
Corporate Dems seem to despise her too, which is good.
And, here are reasons while some people on the left don't like her:
