State Senator Zach Nunn launched his Congressional campaign on July 13 with a promise to “bring Iowa’s record of success to the nation’s capital” and “defeat the far-left’s socialist agenda.”

Although Republicans Mary Ann Hanusa and Nicole Hasso are already running in Iowa’s third district, Nunn entered the race as the clear front-runner for the GOP nomination.

Political junkies may not have Newt Gingrich to kick around much longer. His whole presidential campaign staff quit yesterday, frustrated by the candidate’s lack of a work ethic.

Iowa Republicans will have fewer chances to kick Mitt Romney around this summer. The former Massachusetts governor won’t compete in the Iowa GOP’s straw poll this August, his campaign confirmed yesterday.

After the jump I have more links on those stories and other Republican presidential candidate news. I’ve got nothing on the Iowa GOP Lincoln dinner fundraiser that was supposed to be held tonight, though, because the state party canceled that event after Donald Trump backed out.

Former House Speaker Newt Gingrich was poised to capitalize on Mike Huckabee’s decision not to run for president. Gingrich announced his Iowa leadership team last week. Chaired by House Majority Leader Linda Upmeyer, who endorsed Gingrich months ago, the high-powered crew includes activist and attorney Craig Schoenfeld as executive director, Iowa House Speaker Pro Tempore Jeff Kaufmann as senior policy advisor, Katie Koberg (former vice-president of Iowans for Tax Relief) as deputy director and Will Rogers as grassroots director.

Huckabee’s announcement sparked a wave of “Iowa is wide open” news coverage, just as Gingrich was set to kick off a five-day Iowa tour. In 2010 Gingrich quietly helped raise $200,000 for the campaign against retaining three Iowa Supreme Court judges, which might have helped him with the social conservatives who were Huckabee’s base supporters.

It all started to go wrong Sunday…
