Fully 55 percent of senior executives say higher costs associated with ObamaCare are their top worry, according to a recent Adecco poll. As Reuter’s reports:

“A lot of firms just don't know how the (law) is going to impact them financially," said Senior Vice President Janette Marx. "If it does increase costs, it causes executives to question whether they can hire more."

Healthcare's prominence as an issue has risen since the 2008-2009 recession, Adecco found: in 2007, only 35 percent called healthcare their top worry.

At least CEOs aren’t alone. Apparently lots of Congress members are confused, too.
