Because she's a U.S. Senator who may be the Vice President soon. That's why people care, even if you don't. You know that already so please spare us the personal commentary masked as a question.
This is exactly my point. You are part of the problem the article was pointing out. I personally, don't care what her opinion is because she's not an expert. Just like I don't care what Trump's opinion is because he's not an expert. The fact that the article says I should shows that it's politically biased, and the hypocrisy of talking about how political motivations are causing problems while simultaneous politically charging your own article is disgusting.
