Republicans hold just a four-point lead over Democrats on the Generic Congressional Ballot for the week ending March 27, 2011. It’s the GOP’s smallest lead since early October 2010.
The GOP has been consistently ahead on the Generic Ballot since June 2009, leading by as much as 12 points and as little as three. The week before Election Day last November, support for Republicans peaked at 51%, the highest level of support either party has enjoyed in the last two years, but GOP support tapered off after that. Democrats enjoyed a seven-point lead on the Generic Ballot when Barack Obama took office as president in late January 2009, but their support has generally remained in the mid- to upper 30s since June of that year.
Republicans lead by 10 points among men and run almost even with Democrats among women. The GOP holds a 12-point lead among voters not affiliated with either major political party.
