Texas Congressman Ron Paul hasn't won any of the 23 Republican presidential primaries or caucuses already in the 2012 history books.

Less than $1 million of that was spent by Romney's official campaign, while the pro-Romney superPAC Restore Our Future — which has almost exclusively engaged in negative advertising this year — spent $5.7 million.

That's compared to $220,000 spent on ads last week by the superPAC supporting former Pennsylvania Sen. Rick Santorum.

The U.S. Food and Drug Administration has sent a warning letter to the maker of a caffeine inhaler that's marketed around college campuses. The agency says it's concerned about misleading claims about the product and its safety.
