Reality is reality.
People on the right are not attracted to being newscasters.
Geting right wing people wanting to be newscasters has about as much chance of success as geting Peta members to work in slaughter houses.
It will not happen. Human nature does not change. Right wing news people almost always slide sideways into the news business. Rush got into news talk when the Disk Jockey business died. You will also find that many so called right wing media people, just play a one on TV. Novak is an example. His job is to play a right wing jouralist... and play it badly. Novak is very good at doing the right wing thing poorly. Ask Al Hunt how good Novak is at doing badly.
What are you smokin'? Does the name Brit Hume ring a bell. Or Tony Snow. On Alan Keyes show, was he not discussing current events aka news.
What about John Stossel on ABC? Peggy Noonan started at CBS. And slowly but surely, people who were only able to comment in print on the editorial page are more and more on TV as pundits, Coulter, Malkin, Krauthammer, Barnes, Sammon...
Lack of opportunity is not the same as lack of desire, as any sailor can tell you.
