Politico puts it like this:
The departure of Cheney, 47, from the race would clear the way for Enzi, 69, to handily win a fourth term. Wyoming has not elected a Democrat to the Senate since 1970.
The younger Cheney never got much traction. The Wyoming GOP establishment, including the two other members of the congressional delegation and former Sen. Alan Simpson, quickly coalesced behind Enzi. A first-time candidate, she even clashed with local Wyoming newspapers.
Since July, she has struggled with a series of setbacks.
If only Papa Cheney had cut his losses this quickly in Iraq.
