Mitt Romney starts the week having undergone a transformation.
For almost a year, he tried to portray himself as the grown-up in the Republican race for the presidential nomination. Now, over the course of two debates and countless Florida campaign stops, the buttoned-up businessman is showing that he can get tough.
This shift has upended the yin-yang dynamic that has been playing out for weeks between the passionate, fiery Newt Gingrich and the staid, steady Romney.
One of the guests in the congressional gallery at last week's State of the Union address was Roxana Delgado, an advocate for soldiers returning home with traumatic brain injuries. Her husband, an army sergeant who NPR profiled in June, 2010, had been dramatically affected by the concussion he received from a roadside blast in Iraq.
Many investors are expecting Facebook to file papers for an initial public offering sometime later this week. The company, which was founded in a Harvard dorm room less than a decade ago, is expected to be valued at nearly $100 billion by Wall Street.
And if these early reports are true this is shaping up to be the biggest Internet IPO ever.
