Republicans have opened a 12-point lead over Democrats on the Generic Congressional Ballot for the week ending Sunday, October 31, 2010. New Rasmussen Reports polling finds that 51% of Likely Voters nationwide plan to vote for their district’s Republican congressional candidate, while 39% are opting for the Democrat.

If these results hold, it could lead to the election of more Republicans to Congress than at any time since the 1920s.
