From Zogby:

“A majority of likely voters (72%) believe that a modern American electoral tradition will hold and the President’s party will lose seats in the upcoming 2010 Congressional elections. Forty-one percent of likely voters believe the Democrats will lose seats, but not the majority in either the House of Representatives or the Senate while nearly one-third (31%) believe Congressional Democrats will lose at least one of their two majorities.

“Only 5% believe Republicans will lose seats in the 2010 elections and 14% say it will be a close election and there will not be a major shift either way. Even a majority of Democrats surveyed (56%) believe their party will lose seats in the election, while a majority of Republicans (54%) believe they will gain the majority in at least one house of Congress.”
