DES MOINES, Iowa -- As video of Mitt Romney's remarks at a private fundraiser was circulating on the Internet Monday afternoon, Paul Ryan was reminding supporters of a different set of closed-door remarks: President Obama's comments to a group of donors in San Francisco during the 2008 campaign.

"Every now and then, President Obama will make these statements that sort of show you what he really thinks. ... I remember that one time when he was talking to a bunch of donors in San Francisco," Ryan told a crowd of about 600 people gathered in a conference room of the Embassy Suites here. "He said people like us -- people from the Midwest -- they like to cling to their guns and their religion."

The mention of Obama's 2008 remarks -- and Ryan's "This Catholic deer-hunter is guilty as charged" rejoinder -- has been a staple of the GOP vice-presidential nominee's stump speech, particularly at campaign events in the Midwest.

On Monday, Ryan expounded a bit more on Obama's fundraiser comment.

"That's just weird," he told the crowd. "Who says things like that? It's just strange."

Ryan also made note of the drought that hit much of the Midwest earlier this year.

"We sure could've used this rain a couple of months ago," he said. The rally -- at which Ryan was introduced by Gov. Terry Branstad (R) and Iowa GOP Reps. Tom Latham and Steve King -- was originally slated to be held outside but was moved indoors due to rain.

A U.S. Drought Monitor report released last week showed that two-thirds of Iowa is now in "extreme or exceptional drought," according to the Associated Press.
