In sourcing the statistic, it turns out Democrats claim that 14,000 a day are losing their health insurance isn’t really a function of rising health-care costs which the health reforms aim to address. From Politifact:

Holahan and his co-author, using a baseline of 4.6 percent unemployment in 2007, calculated that 2.6 million people would lose coverage if the unemployment rate climbed to 7 percent; 3.7 million if it went to to 8 percent; 4.8 million at 9 percent; and 5.8 million at 10 percent. The estimates took into account people who lost their jobs but then switched to a spouse’s plan or extended their coverage through COBRA, the federal law that guarantees people who lose their job can still get continued health coverage.
Applying Holahan’s calculations to the actual rise in unemployment from November 2008 to June 2009, we came up with 3.2 million people losing health coverage, or an average of 15,238 per day, so it is close to the 14,000 Obama cited.

So the statistic is really about unemployment. On that front, how’s the Democrats’ stimulus bill working out? Oh:
