Shortly after 9-11, Chelsea wrote an article about her "experiences" on that day. She wrote that the first thing that went through her head as she "saw" the towers fall was how they were going to be able to be rebuilt because Bushs tax cuts wouldn't allow it.
That's a blatantly political statement. I have no problem with her right to be political, but neither she nor her supporters should expect to be treated as though she isn't political.
In my opinion, she's 100% "fair game" now.
