The 29th race is not the only race waiting for the final vote tally. The Minnesota Senate race is even tighter. It looks like the margin there is hundreds out of millions. Whatever you think of Al Franken, I thought his statement on the race struck the right tone, especially this paragraph:
The process, dictated by our laws, will be orderly, fair, and will take place within a matter of days. We won’t know for a little while who won this race, but at the end of the day, we will know that the voice of the electorate was clearly heard.
In 2006, Eric Massa exercised his rights as a candidate and waited for all votes to be counted before conceding. In 2008, Randy Kuhl is doing the same. That's a powerful statement about the rule of law.
