The point about Texas being GWB's home is that his image as a "good ol' Texas boy" is entirely that -- an IMAGE. He knew his father had suffered politically because he was very "East coast" and afraid to get dirty. So GWB tried to counteract that before it could begin by capitalizing on his image as the "good ol' Texas boy," even though he's just as East coast as his father was.
This is one of my pet peeves about GWB: there are so many people who don't bother to look past the image! If they did, they'd find a guy who doesn't know anything about politics (except education, and there he's barking up the wrong tree because anybody who thinks vouchers are the solution to the education system's woes is out of touch), whose cabinet members do much of his work for him, who is never allowed to speak without a speech prepared because his aides are too afraid of what he'd say, a hypocrite, a guy who panders to individual groups (Hispanics, the Christian Right) who he has no intention of helping -- but he knows he needs their vote, a guy who claims he went to war but never did, etc. But so many people are afraid to look behind the image he and Karl Rove and Karen Hughes and whomever else had constructed for the media. They like his charisma and think that makes him a good president . . . when in reality, one of the only intelligent things that Bush has done in the presidency is made sure he's surrounded by people who ACTUALLY know what they're doing.
And for anybody who thinks that putting Condeleeza Rice in office means that GWB isn't discriminating against blacks and women . . . I've got an ocean-front condo in Oklahoma to sell you.
