It is interesting after he went from being elected to city council in 1997 his bio says he served 5 years before elected to Congress in 2002. No mention of his mayoral loss in 2001 (or his run for the Texas House from Amarillo in 1984).
All these sites are like that.
Liza Murkowski's senate website biography used not to mention the fact that her dad appointed her, or that her dad was Governor of Alaska (he was indirectly alluded to in her self-description as a "Third Generation Alaskan", though.) Of course I haven't checked since the election.
