Good Morning!

The fate of President Obama's sweeping health care overhaul will be decided today in a wood paneled conference room on the main floor at the Supreme Court. The judges will vote in secret behind closed doors.. We're just beginning to wrap our heads around how big a decision this could end up being. Still, we won't know the final outcome until late June.. stay tuned.

Quietly and without much fuss, the Republican machine has gotten behind Mitt Romney. He's now seen as the likely nominee by the power brokers in the GOP and by the White House. Representative and GOP power broker Paul Ryan expected to endorse Romney today. We'll look at the shifting race with Michael Barone, Paul Gigot and Carl Cameron.
