There is no indication whether she actually voted, though she said she voted for former President Ronald Reagan in 1984.
The records support Whitman's claims that she's been a staunch Republican, even though she didn't register as a Republican until five years after registering to vote in San Mateo County.
And while she has admitted her voting record was terrible, this latest revelation shows a modicum of political engagement over the last three decades.
The episode does raise doubt about Whitman's political skills, though: Wouldn't it be better to admit she failed as a voter and move on, rather than keeping the question of her voting record alive as the campaign heats up?
Jackson West wonders why the Whitman campaign didn't do this digging a long time ago.
