WASHINGTON (AP) _ There is, perhaps, some self-interest behind Texas Gov. George W. Bush's proposal to shield the Internet from sales tax. Seems the whole Bush family is online.

``I e-mail back and forth to ex-President Bush. ... He's pretty literate,'' said the governor and former president's son.

As for the former first lady, Barbara Bush, better known for her gray hair and pearls than electronic wizardry, ``Mom's on there as well. Believe it or not, she's high-tech. She may not look high-tech, but she's high-tech.''

In an hour-long C-SPAN interview for broadcast on Saturday, Bush talked of finding an academic chat room to help his 17-year-old daughters with their English homework. He talked about his favorite history books. He talked about preferring written scripts to off-the-cuff speeches.

But he gave no further clues on The Big Question: his plans for the 2000 presidential race. ``I'm interested. I'm thinking about it,'' he said.
