Wilson got 25% (source). Bush only got 22% (source) .
These exit poll results have margins of error bigger than 3%, so statsitically Wilson's and Bush's showings are about the same. However, the point still stands: the notion that Wilson alienated California hispanic voters and that Bush is winning the back is pure myth.
Bush never campaigned in CA. He wrote the state off. Its the 187 thingy.
The same CNN exit polls that you linked to show Bush recieving 35% nationally.
The CNN exit polls that you linked to wouldn't show Texas results but in the 1988 Gubernatorial VNS polls Bush recieved 49%.
BTW, don't believe everything you read in Time magazine.
