ROCKVILLE - Think India, home to one-sixth of the world's population. Or California plus New York, which together cast one-sixth of the presidential votes in 2000.

Now think Montgomery County, and you get the idea. In the fight to become Maryland's next governor, the scrapping will be toughest on Montgomery County's turf. It is the state's largest jurisdiction, and one-sixth of the people who cast ballots in the 1998 gubernatorial election live here.

And, because of their proximity to Washington and stunningly large collection of graduate degrees, county voters are often referred to as among the savviest in the nation.

"These are people who understand what motions to recommit are," said Republican Robert L. Ehrlich Jr., referring to a legislative procedure. "They really watch C-SPAN."

Registered Democrats outnumber Republicans in the county by almost 2-to-1. But Republican Ellen R. Sauerbrey won about 40 percent of the vote in 1994 and 1998, which means the county - unlike Baltimore City and Prince George's - has no shortage of what pollsters call "persuadable Dems."

All this explains why Ehrlich and his gubernatorial campaign staff are devoting at least one-sixth of their brains to figuring out how best to operate in Montgomery.

Yesterday in Potomac and Rockville, Ehrlich took a tour of various Jewish health and social service agencies as a sort of formal introduction to the county's Jewish community.

In a cafeteria filled with senior citizens eating lunch, Ehrlich told them he had never represented their area before but promised they would soon see his face on television.

"I'm in Montgomery County a lot," he said. "Just about every day."

When he had finished his short speech, Evelyn Besansky asked the only question of the day: "What's your name?"

Ehrlich knows he has much work to do in the county, where polls show his name is significantly less recognizable than that of his Democratic rival, Lt. Gov. Kathleen Kennedy Townsend.

"I would say people don't even know who he is," said Marvin Sirkis, 68, of Gaithersburg, who was exercising in the Jewish Community Center gym as Ehrlich toured it. "If this is where the votes are, he'd better show up more."

Ehrlich is giving the county special treatment, in part because of its unique voter population. It has the biggest proportion of registered independents of any Maryland county, about 18 percent.

And burgeoning Latino and Asian communities represent voters, many of them first-timers, whose political tendencies are not fully understood by the state's best political minds.

Since January, Ehrlich has visited 58 times, his campaign says, for Metro-stop handshakes to fancy fund-raisers.

Townsend's campaign says she has been here even more often. And conventional wisdom says a majority of the county will choose her in November.

But Ehrlich doesn't necessarily need most Montgomery voters as he seeks to become Maryland's first Republican governor in more than 30 years. A significant minority could be enough - and he says he knows what he must do to get it.

He has done more face-to-face politicking in Montgomery than anywhere else, one of the strategies his staff gained from weekly meetings with county officials last spring to learn how Republicans get elected here.

Ehrlich's first television ad, a biographical spot, will air in the Washington suburbs. He has a campaign office in Bethesda and is about to open another in Rockville - making Montgomery the only county where he has two offices.
