Kerry and Bush bios are incomplete

Why don't the biography pages of either George Bush or John Kerry mention the elections they each lost trying to run for the House of Representatives?

In 1970, Kerry ran and lost the Democrat primary among a group of anti-war leftists. When Kerry ran and lost in 1972, he again ran and lost on an anti-war platform, this time in the general election. To me, this indicates that he was MOST proud of his actions AFTER the Vietnam war than he was of his actions while in combat.

In 1978, George Bush ran for the US House but lost to a Texas State Senator named Kent Hance.
