Republican presidential candidate Newt Gingrich visits western Iowa

Omaha, NE – GOP presidential hopeful Newt Gingrich says his campaign isn't just about a new leader, but about changes in Washington.

Gingrich, the former Speaker of the U.S. House, visited Council Bluffs Friday morning during a tour of western Iowa. He's among several presidential candidates or hopefuls to visit Iowa within recent weeks.

Gingrich says economic improvement is his top priority. He believes an American energy policy that includes coal, nuclear power, wind energy, and biofuels will stimulate economic growth. Gingrich says economic stability can also be achieved by cutting taxes and ending the estate tax.

Texas Congressman Ron Paul has declared his candidacy for president and set up an office in Iowa. Reports say former Minnesota Governor Tim Pawlenty will kick off his presidential campaign next week in Des Moines.

Businessman Herman Cain has also visited Iowa as he considers a 2012 campaign for president.
