The first estimate of the nation's second quarter GDP came out this morning from the Commerce Department, and the best thing you can say about it is that it could have been a lot worse. The economy grew at 1.5 percent in the second quarter, which is down some from the first quarter's reading of 2 percent. But the expectation from economists - depending on which survey you believe - had been down to 1.3 or 1.4 percent.
