A major downside to being a broadcast news analyst is also a major upside. You come into the public eye. That's a double edged sword because it means people love you, but it also means people hate you. Funny how that works, right? Whenever someone is in the public eye, there is bound to be criticisms drawn on them. Sometimes those criticisms are fair and part of the job, other times they are less relevant and can be hurtful.
Don't think that this is just a cushy job that anyone with a pretty face and smooth voice can do. You'll need a bachelors degree for most of these jobs, or at the very least lots of training and interest in journalism. These aren't dumb models turned news anchors. These are true journalists that have worked hard to get on the desk.
