But a new Rasmussen Reports national telephone survey finds that while 64% say a GOP takeover of the House is likely, only 34% believe it is Very Likely. Still, that’s up eight points from January when 26% said Republican control of the House was Very Likely. Twenty-five percent (25%) think that change is unlikely, but just six percent (6%) say it’s Not At All Likely.

Similarly, 56% think Republicans are likely to win a majority in the Senate in the upcoming elections, but just 24% say it is Very Likely. Thirty-one percent (31%) say GOP control of the Senate is not likely, with seven percent (7%) who believe it’s Not At All Likely to occur.

Interestingly, while roughly two-thirds of Mainstream voters say Republicans are likely to win both the House and Senate, most of those in the Political Class believe a GOP takeover is unlikely in either case. 

Forty-seven percent (47%) of all voters say there will be a noticeable change in the lives of most Americans if Republicans win control of Congress, up slightly from 43% in February. Twenty-eight percent (28%) don’t believe GOP leadership of Congress will result in that kind of change, but another 25% are not sure.

The survey of 1,000 Likely Voters was conducted on July 14-15, 2010 by Rasmussen Reports. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC . See methodology .

Given the current makeup of the House, Republicans would have to pick up 39 seats to take control. To win the Senate, the GOP would need to add 10 seats to its current 41. Most political analysts think a Republican takeover of the House is possible but put control of the Senate out of reach.

There are currently nine states in the Toss-Up category in the Rasmussen Reports Senate Balance of Power rankings. Not counting the Toss-Ups, current projections indicate that Democrats can probably count on having 49 Senate seats after Election Day, while Republicans will hold 42.

A slight majority (56%) of Republicans think a GOP takeover of Congress will make a noticeable difference in the lives of most Americans, and pluralities of both Democrats (44%) and voters not affiliated with either party agree (41%).

One-in-four GOP voters are not sure whether that kind of change is likely if their party wins control of the Congress. Perhaps that’s explained in part by the feeling of 72% of Republican voters that GOP members of Congress have lost touch with the party base throughout the nation over the past several years.

Republicans predictably are confident that their party will win control of both houses of Congress. Fifty-four percent (54%) say a House takeover is Very Likely, while 42% say the same of the Senate.

Democrats are closely divided when asked about the House, but just nine percent (9%) believe GOP control of the Senate is Very Likely.

Among unaffiliated voters, 39% say a change in the leadership of the House is Very Likely, while 21% believe Republicans are Very Likely to win control of the Senate, too.

Republicans continue to lead on the Generic Congressional Ballot as they have for over a year now, which means that voters are more likely to vote for their district's GOP congressional candidate over his or her Democratic opponent. 

Voters also trust Republicans more than Democrats on nine out of 10 key issues regularly tracked by Rasmussen Reports, including the economy, health care and national security.

At the same time, 65% of all voters nationwide believe the country would be better off if most incumbents in Congress, regardless of party, were defeated this November.

Voters are evenly divided over the notion that a group of people randomly selected from the phone book could do a better job than the current Congress.

Thirty-five percent (35%) think Republicans and Democrats are so much alike that an entirely new political party is needed to represent the American people. 

But then 68% believe the nation’s Political Class doesn’t “care what most Americans think.” Only 15% believe the Political Class is interested in the views of those they are supposed to serve.

Just 23% of voters nationwide believe the federal government today has the consent of the governed. Sixty-two percent (62%) say it does not
