DES MOINES, Iowa (AP) — Rural southwest Iowa state Sen. Joni Ernst has emerged as a front-runner in what once was a jumbled field of Republicans hoping to succeed retiring Democratic U.S. Sen. Tom Harkin. Ernst has managed to bring together warring factions of the state and national GOP before the primary. She has aired ads featuring her firing a handgun at an indoor shooting range and talking about her childhood experience castrating hogs.

Today’s (Tuesday’s) primary is significant because Iowa, a traditional swing state, is expected to play a key role in the race for U.S. Senate control this fall. Republicans need six seats to gain a majority. Neither party will have the power of incumbency in the race. The GOP views Democratic U.S. Rep. Bruce Braley, the assured nominee, as vulnerable.

COUNCIL BLUFFS, Iowa (AP) — A transient was arrested following a brief standoff in Council Bluffs, Monday. The Council Bluffs Police Department says 29-year-old Kevin Richard Bequette was taken into custody at around 10:30-a.m., after the Omaha Metro Fugitive Task Force tracked Bequette to a residence and attempted to apprehend him on a warrant for a parole violation. The man is accused of locking himself inside a detached garage behind the home.

Authorities communicated with Bequette for about 45-minutes, during which he threatened to harm himself. At around 10:30-a.m., officers could smell smoke coming from the garage. They broke into the structure and took Bequette into custody without further incident.

Damage to the garage was described as minimal.

Police Capt. Todd Weddum says Bequette was checked by medics at the scene, but he did not require any treatment.

OMAHA, Neb. (AP) – Iowa utility officials say the Obama administration’s ambitious plan to cut carbon dioxide emissions from power plants is likely to increase costs. The plan announced Monday calls for carbon emissions to be cut by 30 percent by 2030 when compared to 2005 levels. But utilities and state officials say they’ll have to review the details before they know how Iowa will be affected.

Regi Goodale with the Iowa Association of Electric Cooperatives says it’s just a question of how much electric bills will increase because of the new regulations. Iowa utilities invested heavily in wind power over the past decade and improved the efficiency of existing power plants. Mark Douglas with the Iowa Utilities Association says the state may be in a good position because of those past efforts.
