Democratic race again...short one, promise!

One thing I've noticed about the race between the two presumptive nominees, is that everytime, win or lose, be it a caucus or a Primary, Obama acknoledges Clinton, and mentions how it was a "good fight" (or words to that effect), and asks the crowd to give her a round of applause. Not once has Clinton done the same. To the Clinton team it may look like she's being strong by not even acknowldging her fellow Democrat, and looking forward to the race against McCain. From this standpoint, it simply lacks class , and plain manners...
