WASHINGTON - Bill Clinton has always had a flair for political drama. Now it looks like his just-in-time recovery from heart surgery, allowing him to campaign for John Kerry in the election’s closing days, may provide a jolt of excitement that any candidate would covet. Democratic strategist Donna Brazile says she started getting phone calls and e-mail as soon as word got out about Clinton’s planned appearance Monday with Kerry in Philadelphia, with messages like: “He’s back! The Comeback Kid!” She predicts “a great, electrifying last week of the campaign.”
