Congressman A says more Republicans in Congress will lead to more gridlock and stand in the way of President Obama's agenda to create jobs and make needed reforms to our economy.Congressman B says we need more Republicans in Congress to act as a check and balance on runaway Washington government that is bankrupting the country and mortgaging our children's future.A majority of voters agrees that more Republicans are needed to provide a check and balance by 51 to 40 percent, including a two-to-one margin among Independents (61 to 28 percent).
In his book on midterms, Horses in Midstream, Andrew Busch provides some context:
[The midterm's] task has been not merely to check in a simple and negative sense, to prevent action by the president or his partisan allies, though it can most assuredly do that. It task is also frequently to balance in a much broader sense: to end the dominance of one party and to clear the way for dominance by the other, and to serve as a positive tool for innovation and the long-term rejuvenation of the opposition party.
