Clinton Shifts to Aggressive Campaign Style

Facing a tightening race in Iowa and increasing criticism from chief Democratic rivals John Edwards and Barack Obama , Hillary Clinton has shifted from an above-the-fray style when she led more comfortably in polls to a more aggressive approach, the LA Times reports. Her new TV ads defend her electability and blast Obama as too inexperienced. "She's not going to be on the sidelines," says one adviser.

Recent polls show a three-way tie in Iowa, and Clinton is not alone in hardening the message: Obama, despite his vow to avoid negative campaigning, increasingly portrays her as the poster girl of a discredited Washington establishment. And Edwards accuses the former first lady of defending a corrupt political caste of which she has long been a member.
