In some states, polls are already open this morning. It's Super Tuesday and 10 states are scheduled to hold nominating contests. At stake are 437 delegates.

Rebekah Speight spotted the familiar profile on a McNugget left on her child's plate. After stashing it in the freezer for three years, she auctioned it off on eBay. Her church's summer camp will benefit from the winning $8,000 bid.

Navy Secretary Ray Mabus says he wants personnel to adapt to the 21 century. He announced the Navy will give sailors breathalyzer tests and drug tests before they report to duty on a ship. The Marines will adapt a similar program next month.

NPR's Dan Charles has been looking into the problem of weeds that America's most widely used weed-killer won't kill anymore. It's a sneak preview of a story that will air later this week.

First responders never know what they'll find when they get called to an accident site. Sometimes crews have to rescue dairy cows from collapsed barns, evacuate horses during wildfires or move pigs off the highway after an accident.

Mitt Romney is hoping to return to front-runner status but Rick Santorum, Newt Gingrich and Ron Paul are trying to prevent that.

Morning Edition has four reports on Monday's campaigning leading up to Super Tuesday's 10 primaries and caucuses.

NPR's Don Gonyea was traveling with former Senator Rick Santorum in Ohio.
