At this year's fishing contest on Lake Winnebago in Wisconsin, they weren't just fishing for sturgeon. People arriving to fish parked their cars too closely, and the ice gave way. No one was hurt but three dozen vehicles were pulled out of the lake.

A line of severe storms moving across the Midwest left death and destruction in its wake early today.

The storms moved through Kansas and Missouri overnight, destroying one trailer park and leaving at least one dead in Buffalo, Mo.

The hardest hit area is Harrisburg, Ill., where authorities say at least six people have been killed after what is presumed to be a tornado raked the town before dawn. (Note: in situations such as this, details such as the number of people killed and injured change as more information comes in. We will be updating this post.)

Former Massachusetts Gov. Mitt Romney notched two big wins Tuesday, upping his Republican presidential delegate count and taking modest-plus momentum into the week leading up to Super Tuesday on March 6.

With the Michigan and Arizona primaries in the history books as Romney's fifth and sixth victories, we're looking ahead to Super Tuesday, when presidential contests will be held in 10 states and 413 delegates will be up for grabs.

Rick Santorum and his campaign will likely look back on Michigan's 2012 primary not only as a heartbreaking loss in the battle against Mitt Romney but also as a historic lost opportunity.

The upstart former senator from Pennsylvania was within a few percentage points of toppling the wobbly frontrunner in a state that really mattered.

Unlike his earlier wins in caucus states (Iowa, Colorado, Minnesota) and a nonbinding "beauty contest" (Missouri), a win in Michigan meant a real cache of committed delegates.

New research indicates that five days after major NASCAR races, there is a measurable increase in traffic accidents caused by aggressive driving.

And while Mitt Romney was eking out that win in Michigan, he pretty much walked away with yesterday's Arizona primary. Romney was expected to win in Arizona, but he walloped his closest challenger - that would be Rick Santorum - by 20 percentage points. Helped, in part, by the support of the last Republican presidential nominee, Arizona Senator John McCain.

And while all the attention was on Michigan throughout the night, NPR's Ted Robbins reports that in the all-important delegate count, the Arizona win counts for nearly as much.

GOP presidential hopeful Mitt Romney turned back challenges from former Pennsylvania Senator Rick Santorum in Arizona., where Romney won easily, and in Michigan, where he eeked out a close win in the state where he was born. Before Tuesday night, Romney's last primary win was in Florida a month ago.

And that brings us to our last word in business on this Leap Day: a rare proposal. Traditionally in many European countries Leap Day was considered the only day when a woman could propose to a man. And one restaurant in Swindon, England seems to be capitalizing on that.

NPR's business news starts with an invitation from Apple.

Journalists were invited yesterday by Apple for a product event next month. And that was enough to send the company shares to another all-time high. There's wide speculation the event will introduce the next generation of its iPad tablet. The iPad 3 is expected to have a faster processor and a high definition display.
