Gallup says Americans are showing a preference for new Republican candidates

A Gallup poll indicates Americans are intent on changing the makeup of Congress in the 2010 midterm elections, with 75% of the American people saying Congress would be improved if most incumbents are replaced with new members. And it's Republican newcomers who are the choice of a majority of Americans, according to Gallup:

In a year when Americans are dissatisfied with the state of the nation and give relatively low ratings to the president and Congress, it is not politically beneficial to be either an incumbent or a member of the ruling party. That is reflected in Americans' preference for a Republican newcomer over other types of candidates they may have a chance to vote for in this fall's midterm congressional elections.
