John Kerry and Newt Gingrich, two of the nation's deep political thinkers with very different view points, will take on the environment in a debate next week. Kerry, last year's Democratic presidential nominee, and Gingrich, a contender for the Republican nomination this year, are influential voices in their respective parties. Both have published books about the environment. When it comes to presidential politics, this debate may go down in the history books as also-ran vs. already-ran, but when two figures of this stature go head-to-head on the environment, we'll want to watch. Check CSPAN listings if you can't catch the event in person at Russell Senate Office Building in Washington, Tuesday, April 10 at 10 a.m.
