President Obama, Treasury Secretary Tim Geithner and a passel of regular people participated in a messaging event in the East Room of the White House this morning. Mortgage rates are lower, and the White House wants folks to take advantage of that stimulative news. The communications skeptic in me, however, wonders about the wisdom of messaging events inside the White House that deal with bread and butter issues. Granted, the White House couldn't schedule a domestic trip so soon -- though Obama could always go to Annandale, VA -- and this White House does like to use the bully pulpit to educate. But there's a risk of both overexposure -- too many small East Room events and the sense that the president is playing Suze Orman -- and underexposure -- why isn't he standing in front of a house somewhere?
