Coming in this Sunday's Currents, we welcome two new voices: Mark Bowden and Michael Smerconish. Former Inquirer staffer Mark Bowden is author of the celebrated "Black Hawk Down" and national correspondent for the Atlantic Monthly. He offers a column titled "The Point." He will be joined by Michael Smerconish, Daily News columnist, radio opinionator at WPHT-AM (1210), and TV host on Fox and CNN. Michael's column will be called "Head Strong." They join Trudy Rubin's "Worldview" and our potent line-up of writers to make Currents - always a must-read - even more of a Sunday event. Welcome aboard, gentlemen.
