My big pet peeve is reporters who play along with politicians who have no intentions of returning to life in their home towns or even their home states. I doubt Evan Byah spends much time in Shirkieville, or even Indiana these days, but if he started waxing nostalgic about the Greatest Little Place In The Greatest State The World Has Ever Known,it's unlikely that any reporter would ever call him on it.
And it's fine that politicians often end up shifting their careers to Washington. It's where their jobs are, increasingly where their families have bonds, and where their post-politician careers are likely to be the most lucrative. It doesn't even mean Evan Bayh thinks Indiana sucks. But it does mean he's left it.
