I believe this to be a calculated career public relations action. Start out conservative and become a prominent supporter of conservative causes for a few years and then have a “transformation” to embrace the truth of liberalism. It’s a great career boost and money maker for those who convert. Arianna Huffington became a leader among liberals this same way. Purely a busines decision.
Either that or she was sucking up to her Conservative boss and now is sucking up to her liberal peers now. I’m just a little disappointed. I thought she was above the “my opinion is so important because I’m famous” crap.
