She's a superstar at work and a supernanny at home. She usually even has enough left in the tank to be a superwife at night.

You've seen her. She's your your sister, your mother and your grandmother.

She could even be you.

Now there's another moniker to add to that list.

Supervoter.

She's a woman - of course - who exercises her voting power in a way not even Superman could suppress.

Supervoters cast ballots faithfully. They vote in off-year elections. They vote rain or shine. They vote for president or dogcatcher. And they sway elections big-time.

They make up a voting bloc that even Barack Obama, for all of his historic fund-raising, record voter registration, and community organizing, may have overlooked.

But Emma Tramble is one step ahead.

Tramble, 46, a onetime volunteer for the Obama campaign, believes she has tapped into the power of the supervoter - right in her own backyard.

Her concept is simple: Target the supervoter and bet on her wielding her power of persuasion to get the whole family to the polls.

Tramble calls her initiative My Family Votes!

On board early

She saw firsthand how deft Obama's volunteers were in canvassing voters - particularly young, first-time voters.

Tramble likes to joke about getting all of her education in West Philly: Huey Elementary, Sayre Junior High, West Philadelphia High, and the University of Pennsylvania.

So if there's one thing she knows, it's West Philly. Especially the women who live there.

She noticed that these women were also usually heads of their households, working moms and grandmoms her age or older making $70,000 or less a year, who sometimes had one or two generations of the family living with them.

And they were supervoters.

So, Tramble figured, why not take advantage of Obama's energy as a way to get people to vote Nov. 4 - and, even more important, to stay involved after the election?

Which was how she came up with My Family Votes!

Logical targets

Tramble and her army of volunteers ask three simple things: Make sure everybody in the house is registered to vote. Tell neighbors about the program. Make sure everybody in the house goes to the polls.

And if these supervoters can get their loved ones to cast ballots, imagine the increase in turnout among Philadelphia's 800,000 registered Democrats, half of whom skipped the primaries.

"People don't realize the power of the vote," Tramble says. "If everybody voted in Philadelphia, we wouldn't need the middle of the state to get Obama elected."

My Family Votes! (www.my

familyvotes.com) may target only a few zip codes in West Philly, but it sure has a corporate feel.

Which is to be expected from Tramble, a former business analyst who made her living by coming up with strategies to ensure that corporations ran smoothly.

For as long as she can remember, Tramble has had a passion for politics and community. At 7, she started watching gavel-to-gavel coverage of Democratic and Republican conventions.

When the Rev. Dr. Martin Luther King Jr. was assassinated, Tramble recalls, she thought: "Dr. King is dead. Now what are black people going to do?"

So far, My Family Votes! has made 870 calls, each one representing three prospective voters. Some of the women whom Tramble has called have volunteered their own time.

The power of engagement is empowering.

"Apathy is the worst suppression tactic," she says. "If you feel powerless, you can't do anything."
