Most analysts have a assumed that Al Franken stands to gain
ground if an estimated 1,600 improperly rejected absentee ballots
are counted in the Minnesota Senate.
Nate Silver notes that a pre-election
poll (PDF) showed Franken up by 8 percent among absentee
voters, which according to what he calls a "crude estimate,"
would mean a net gain of 128 votes for Franken -- a substantial
portion of his 192-vote deficit. However, the poll was conducted
by the Democratic firm Public Policy Polling, and it also showed
Al Franken with an overall lead of 5 points in the Senate race.
Given that Franken's general level of support was substantially
overstated in the poll, it likely overstated his support among
absentee voters as well. The Franken campaign wants these votes
to be counted and the Coleman campaign does not -- after all, in
a recount, it's always the team that's behind that wants to
expand the universe of ballots and the winning side that wants to
freeze them in place -- but until we get a better idea of how the
absentee ballots in question are distributed among the counties,
there's no empirical reason to believe that Franken actually
would make significant gains, even if they were counted.
