The Lowe brothers get political

The Lowe brothers have taken on presidential politics . . . at least on primetime TV. Which one has the juicier role?

Rob Lowe gets to bed Calista Flockhart's Kitty Walker on Brothers & Sisters, as he portrays a smooth-talking, charismatic Republican senator seeking the presidency.

Meanwhile, Chad Lowe tries to assassinate a president and frame a terrorist for the deed on 24, as he portrays the deputy chief of staff who's trying to save the country from the commander in chief's perceived weak response to a string of terror attacks.

Rob's turn as an earnest Democratic speechwriter on The West Wing notwithstanding, who gets bragging rights in the Lowe family for the best political character?
