Washington (CNN) - One of the top non-partisan political handicappers is increasing his forecast of how many seats the Republicans may pick up in the House of Representatives this November.
The Rothenberg Political Report is out with a new prediction Tuesday pointing towards likely GOP gains from 37 to 42 seats in the chamber, up from 28 to 33 seats from their most recent forecast. The Republicans need a net gain of 39 seats to take back control of the House.
The Rothenberg Report adds that larger GOP gains in the 45 to 55 seat range are possible.
"National and local polls continue to show further deterioration in Democratic prospects," says Stuart Rothenberg, editor and publisher of the Rothenberg Political Report. "The next few weeks will be crucial, as Democratic incumbents seek to drive up Republican challengers' negatives and strengthen their standing in ballot tests."
The other leading non-partisan political handicapper, the Cook Political Report, forecasts a net gain of at least 35 seats and possibly as much as 45 seats.
Last week University of Virginia political handicapper Larry Sabato estimated that Republicans would pick up 47 House seats in the midterm elections.

The GOP can't gain seats or we can kiss America goodbye. Bush and his cronies almost buried this country and turn it into a neo-fascist dictatorship. President Obama and the Democrats have given the country back to the people and they know what a Constitution is. They're doing everything they can to repair the economy that the GOP destroyed.
It's not going to happen overnight, but if the GOP gains seats, it won't happen at all.
Yeah! Nancy has to go set in the swamp with the rest of her Rats.

We will get what we deserve for forgetting so soon what these heartless money grubbing traitors did to our country just 2 years ago.
Endlees war
Endless Spending
Endless tax cuts for the rich
Endless Focus on your personal lives
Endless hipocrisy
If Americans want to take the country back to Republican politics that gave corporations such as Wall Street bankers, Insurance companies, credit card companies control over our lives and shipped our jobs overseas... good luck America!
They will finish what they started and they will continue to deregulate the banks, take away health care reform and take us back to bank-financed student loans. The gap between rich and poor will widen, and the middle class will continue to disappear. If that is what Americans want...go for it! You deserve what you get!
How soon we forget!!!
The growing evidence that Americans are getting dumber......vote back the idiots who got us into this mess!!!!!
Wow, I am astonished at the failure of Americans to understand the issues involved. These folks must want tax cuts for the rich, another war, the middle class diminishing further, higher unemployment etc,.
Vote for the Party of NO, the Party of NO ideas, Stupid.
And that is probably a conservative number!!!
Can't wait until November to create a new "Mandate". Remember when Obama was running around saying that after he was elected? Well I believe the "mandate"is getting ready to change severely for the party of spend spend spend.....
we really need to put focus back on education, theirs way too many dumb people in this country.
I think we need a military rule in this nation....if senate says...entitlements...jail them, if financial guys say derivatives jail them, if any employer hires illegal, just mercilessly jail them.....if any one cheats jail them.....we need to pour money only on American soil...bring back Manufacturing and R & D...they are going overseas...hurting America...wake up....Reagan ruled 8 years, Bush ruled 8 years...what did they do to the nation....looted...looted looted the nation,.....true..true, and true...
Just because someone makes a prediction doesn't mean that it is true. CNN, stop selling news entertainment and start selling good news journalism.
Takin back the house and running Pelosi out!
How much money is the Rothenberg Political Report putting soen on its prediction?
I really laugh when I see these predictions. How can anyone do it at this stage? Fifty something days to the election is a century in politics. A lot are going to happen during this period thus altering all these wishful thinking mentality.
Are you people just blinded in one eye and can't see out the other.
It took the republicans 8 years to put us in this mess and you expect Mr. Obama to get us out in 2 years. "PEOPLE PLEASE GET REAL".
Give the man a chance!
Of course a CONSERVATIVE think-tank is going to give the GOP good news.
Sure, America, is going to give the GOP power back after the damage they did?! IF so, we are in serious trouble.
In NOvember vote NO for the Party of NO!
