There is an interesting dynamic playing out in Maryland’s 4th district. Al Wynn (D), who has represented the district since 1993 is being challenged by a Donna Edwards (D), a political newcomer who is a very solid candidate and who has been steadily gaining momentum ever since she whooped Wynn in a one-on-one debate some weeks back.

This morning, Donna Edwards was endorsed by the Washington Post. Please take a moment to read the endorsement and send it around to as many Marylanders as you can.

Excerpt from Washington Post Endorsement:

On the war in Iraq, Ms. Edwards has scored points by attacking Mr. Wynn as Maryland’s Joseph I. Lieberman — a supporter of the war portrayed as too close to the Bush administration. Mr. Wynn backed the war at the outset, but he has since recanted, saying he was misled by bad intelligence. More to the point of today’s debate, both candidates are calling for a U.S. withdrawal, a scenario that we believe would leave chaos in its wake.

Mr. Wynn insists he has been a successful pork-barrel politician; we suspect Ms. Edwards, razor-sharp and relentless, would be at least as effective. We disagree with her on some important issues, but we are convinced she would be the more forceful, principled and effective representative. And while her insurgent candidacy is an uphill battle, it should put Mr. Wynn on notice that voters expect quality representation in Congress, not just a local political boss.
