The house needs to remember that they are not on a crusade to undo everything obama. Rather the house needs to be aware of the issues that the electorate hold dear, the economy, American values and their sons and daughters in the military.
If the house remains true the American values, all the rest of the changes will follow as will the future make-up of the senate and the presidency.
If the house goes ideologically too far to quickly, they risk alienating the voters that elected them and will lose the initiative.
I think winning the house this time and doing some damage in the senate puts us in the best position to remove obummer in 2012.
