(CNN) - Though all 435 seats in the U.S. House of Representatives will be up this November, the battle to control the chamber next year will come down to a much smaller number of congressional districts scattered across the country. CNN has identified the top 100 House races, which we’ve dubbed “The CNN 100,” and will profile one of these races at random each day for the final 100 days leading up to the election. These seats run the gamut both politically and demographically: red states and blue states, urban and rural, open seats and seats with incumbents facing their first competitive race in years. Some are highly competitive, while the race is still developing in others. We’ve listed the CNN 100 below in two groups: the 50 most vulnerable seats, and another 50 races worth watching.

In Lee County, FL, my republican congressional representative lives in California with Sonny Bono's second wife. Since he is not on the list, it appears that our own carpetbagger is not 'vulnerable.'
When the Bamster won in 2008 and when Pelosi/Reid began their reign of error in 2006, the day after the elections, the news media trumpeted, "The people have spoken! They want change!"
I'm making a prediction today that the news media will cry the day after theis November's election, lamenting, "The people have thrown a temper tantrum!" (See Peter Jennings the day after the 1994 routing).
...and all because smart voters can clearly see with their own eyes, from their own daily experiences, that SOCIALISM. DOES. NOT. WORK.
But feel free to say we're having a temper tantrum... just so long as we get to eject National Socialists from the congress.
I'm only concerned with Bachmann's seat. I just want to see that witch gone.
It is interesting to note that most of the so called "contested" races are those in which a Democrat is the incumbent. So if the GOP does not fare as well as it expects, could this be viewed as a rejection of their politics and an endorsement of President Obama? Food for thought.
a GOP rule is UNTHINKABLE
I understand why Reagan succeeded now despite his lack of intelligence, his secretary of state was amazing, Shultz is the reason Reagan did as well as he did
Bush and Bush Jr. did not have a Shultz and that is why we are in the pickle we are in... we had Rummy and Powell... Powell needed more spine and Rummy was a DISASTER
Albright and Clinton were and are pretty good
19 out 100 Republican and only a handful which are not subject to ACORN, SEIU, DEMOCRAT voter fraud.
The DNC is putting out a bulletin for all libs to take some black panther training courses of how to intimidate voters and commit voter fraud.
Voter fraud is to Democrat what Gasoline is Automobile.
Chicago lib libs like Obama always say vote early and vote often, is it any wonder that every single American with morals, values, honesty, and integrity all have the same thing in common? Which is they vote Republican! Watch, a lib will prove this to be true if they respond to it.
So much hype, so much time on the media's side. THese are guesses; i could do the same thing.
Thank you NRSC for giving us some hope and change. The hope and change that the idiot liberal ran on in 2008 turned out to be doom and disaster for those of us who actually work, pay taxes and take personal responsibility for our lives and can think for ourselves. He has sponsored and propagated class warfare, racism and demean and degraded us ably abetted by the "Nutroots Nation" of liberal, elitist, snobs.
Doing a little turd polishing are we?
Hahahahahahaha.... 45 of the 50 "most vulnerable" are held by democrats. Sucks to be them.
I hope that obnoxious, loud-mouthed jerk Grayson hits the bricks in Florida. He'll probably wind up as a cabana boy for Olberman on MSNBC.
THis is easy.
DON'T vote for any current incumbent. And definitely grid lock these people so they will not be allowed to continue destroying the country.
And if I hear one more person accusing others of being racist just because they don't agree with you I'm going to scream. This could cause a real war.
Where is President Obama ? Why does he not condem this???????
Please do not limit Obama's appearances. He is the president for all Americans. May it be on The View or Jerry Springer shows, Americans are watching. Even God Himself once said," I am the God of all flesh.......". Our president should appear for the high as well as for the low. That is the reason we love him.
Wow, out of the 50 most vulnerable seats, only 5 are Republicans? That should really tell you something, liberals.
Adler has something to worry about. The district was held for a long time by a Republican, but it wasn't heavily Republican. I am sure the the Republican candidate, a former Eagles football player, is like the rest of the party - without a plan other than opposing Obama.
Adler has opposed some Obama ideas like the health care plan. It seems that it could be a toss up. The history says one thing, but the GOP opponent says that they are desperate.
