Over the weekend, Sarah Palin addressed Iowa Republicans at the state party’s annual Ronald Reagan dinner in Des Moines. Looking ahead, Sen. Chuck Grassley (R., Iowa) tells National Review Online that if Palin is thinking about a White House run, she should consider scheduling a few more trips to the Hawkeye State. The Iowa caucus, he says, is “kind of like running for sheriff.”

“Even though she has the ability to generate a tremendous loyal following, that tremendous loyal following is going to be looking for a commitment by her to run for president the way people do in Iowa, which is to spend a lot of time there,” Grassley says. “I have not talked to her about it, but I think she needs to demonstrate that she is willing to spend a lot of time campaigning here.”
