“I wonder if this would be possible for other people, to set up Google news or whatever to do a standard search that turns up items of special interest to right-wingers and lists them on a page when you go to it?”

Would this webpage come close to what you are suggesting? Its closer to Yahoo! than Google, though.

For some reason I keep getting a “page cannot be displayed” response.

The link works, at least at this end. Try going to Townhall.com first and then clicking on the “RightPages” heading at the top of the page.
