The recent Gallup Poll was taken between September 5th and 8th of a nationwide sample of about 794 adults, with a 4 point margin of error. The poll showed that all four congressional leaders, Mitch McConnell & Harry Reid in the Senate and John Boehner & Nancy Pelosi in the House, are not well liked by the general public and all four have upside-down approval ratings -- McConnell (35%-47%), Reid (33%-53%), Boehner (37%-54%), and Pelosi (39%-51%).
The poll also showed that all four were pretty equally disliked by Independent voters. But three of those leaders can at least claim some support from their own political party -- with the numbers for Boehner at 48%-44% among Republicans, while Reid has a rating of 47%-40% & and Pelosi has a rating of 65%-24% among Democrats. It is Mitch McConnell, the Republican Senate Minority Leader who has the worst numbers, being upside-down even with the members of his own party at 33%-47%.
This could well show why his poll numbers for his re-election campaign in Kentucky have been so low (showing him trailing his Democratic opponent by a few points). Politics is a lot harder when the voters in your own political party don't like you (by a huge 14 point margin).
