Obama's link to America: his BlackBerry

[Commentary] Let President Obama keep his BlackBerry. An off-line Obama isn't just bad for Barack. It's bad for all of us. The president's ability to reach outside his inner circle gives him access to fresh ideas and constructive critics; it underscores the difference between political "victories" and actual solutions; and it brings the American people into a battle we can only win by working together. (John D. Podesta served as co-chairman of Barack Obama's transition team. He is the founder and president of the Center for American Progress and was President Clinton's chief of staff.)
