Gallup tracking of 2010 congressional voting preferences shows Republicans moving back ahead of Democrats, 49% to 43%, by two points their largest lead of the campaign to date. Registered voters' preferences had been closely divided for the last several weeks.

The Democratic Party is preferred by much wider margins for the environment and discrimination against minority groups -- but these are among the least worrisome issues to Americans.
