(CNN) - A controversial new immigration law in Arizona might impact the vote in the mid-term elections later this year. For one, it could energize Hispanics and bring them out in large numbers to vote. University of Virginia political scientist Larry Sabato says it's too soon to tell exactly what the impact might be.

(CNN) - A Pew Research Center study released Sunday found that trust in government is at its lowest point in more than half a century.

The Pew survey comes as a recent CNN/Opinion Research Corporation poll also shows that trust in the federal government is about as low as it was in 1994, when Democrats lost control of Congress.

University of Virginia political science professor Larry Sabato told CNN Radio's John Lisk that there have been many times when government has lost the trust of the people, usually over some scandal, such as Watergate.

In this situation, Sabato said that the frustration with government is due in part to a bad economy and dismay over the recently passed health care reform legislation.
