Dan Bartlett went to work for George W. Bush straight out of college, 14 years ago, when Bush was making his first run for governor of Texas. During the 2000 campaign, Bartlett’s job was to know everything about Bush’s past and Texas record. He has been a constant in Bush’s political life. Now Bartlett, 36 today and the father of three kids under five, is resigning. Which means Karl Rove, Margaret Spellings and Alberto Gonzales are pretty much the last inner-circle Texans still with the President.
