Who’s been turning more heads than any movie star on the Sony lot? With Super Tuesday looming, Vice President Al Gore this week decamped to a Columbia Pictures screening room to practice his delivery for his big California debate.

Why Sony? Federal Elections Commission filings shows that Sony’s exec suites are, like much of Hollywood, very much for the Dems: Sony Corp. of America prexy Howard Stringer’s recent campaign-giving list reads like a who’s who of Democratic politics: He’s dropped $1,000 donations to the Democratic Senatorial campaigns of Hillary Rodham Clinton, New York’s Sen. Charles Schumer, Connecticut’s Sen. Chris Dodd, and Nebraska’s Sen. Bob Kerrey.

A studio spokeswoman said the visit was “strictly business” and candidate Gore did not meet any Sony brass.

That may not be so surprising. SPE chairman John Calley is a Bill Bradley supporter, having elected to donate $1,000 to his campaign June.

Staying out of the fray: Col chairman Amy Pascal. According to the latest FEC filings, she gave to neither of the two Dems, instead spreading a $5,000 donation to Sony’s PAC beneficiaries, many of whom are Democrats.
