Ephrata, Penn.--Last summer Anna Mae Ressler, a GOP committeewoman from this postcard-pretty Pennsylvania town, got a directive from the Republican National Committee: Invite your pastor to a free luncheon to learn the ins and outs of legal political organizing in churches.

Her minister came, as did 100 others from the area, and heard a pitch from a controversial activist named David Barton, author of the book calling separation of church and state a "myth" and founder of Wallbuilders, a Texas group whose goal is "restoring America's religious, moral and Constitutional foundations." While campaign workers handed out registration kits for use in church-based voter drives, Barton presented a slide-show of American monuments, described America's Christian heritage, and explained why he thought it was fine for pastors to endorse President Bush from the pulpit.

"This really is a spiritual battle," says Ressler, who this week is calling the 1,312 Republicans in her precinct, urging them to vote. "The Lord gave President Bush to us in a miraculous way the last time."

This time, though, they're planning to give God some extra help. The churches in Lancaster County, Pennsylvania, have conducted massive voter registration drives in their narthexes, handed out sermons and prayer pamphlets, put voting literature in their tract racks, and held weeks-long voter education programs with conservative speakers. They're now gearing up for round-the-clock prayer vigils for the president.

The frenetic activity in Lancaster parallels efforts to mobilize evangelical Christian voters around the nation. The Bush campaign has a goal of mobilizing an additional 4 million evangelical voters this year. Lancaster County, where Republicans outnumber Democrats three to one, is one of nine Pennsylvania counties in this pivotal swing state that the RNC has targeted for a strong showing. The president campaigned here in July; a few weeks later, former Christian Coalition director Ralph Reed, now a top Bush-Cheney operative, hosted a pastor's luncheon to describe what churches can do legally to register and motivate voters; in September, White House Office of Political Affairs director Matt Schlapp held a closed-door meeting with 275 Lancaster GOP activists.

The first step was voter registration. "Our voter registration people have worked with churches to encourage non-partisan voter registration drives, realizing that we will probably get three-quarters to seven-eighths of them as Republicans," said Lancaster County Republican chairman David Dumeyer, standing outside the Lancaster County GOP trailer at a huge annual agricultural fair.

Ressler spent the fair trying to sign up new voters. "The Christian community sees this as a very pivotal election," said Ressler, a redhead wearing a blouse decorated with American flags. Shaking hands with registered voters as the fragrance of fried oyster sandwiches and funnel cakes drifted nearby, she said: "George Bush is trying to keep alive America's heritage...This business of talking about separation of church and state is so ridiculous because there is no such thing in the constitution."

For the first time in several years, Ressler is calling Republicans in her precinct who never vote, pleading with them to fulfill their civic duty.

After the RNC luncheon last summer, the Worship Center in Leola-which attracts about 1,600 people to its weekend services--organized a voter registration area and offered brochures for a four-week program called Prayer & Patriotism. Though officially non-partisan, the program featured all conservative speakers from groups like the Pennsylvania Family Institute; Faith and Action, whose mission is to "reintroduce the Word of God into the public debate surrounding legislation and policy matters;" and the Rev. Peter Marshall, an evangelist whose ministry focuses on "the urgent necessity of Christians recovering the original American vision."

The Bush campaign gave the county GOP a goal of registering 7,000 new voters. To the surprise of local party officials, they got more than 15,000 registrations--in large part by papering evangelical churches with voter registration forms. "That's the strategy, there isn't any doubt," says G. Terry Madonna, Pennsylvania's top political pollster and director of the Center for Politics and Political Affairs at Franklin & Marshall College in Lancaster. "That's what the party is telling them to do, and they are following through."

On Election Day, Ressler will coordinate what is called the "striker-caller program." When Republicans who've pledged to vote sign in, their names will be crossed off a list. Late in the day, those who haven't yet shown up will get a phone call. Ressler will also hand out voter guides assembled by a local group affiliated with the Christian Coalition. But, she says, the guides are less important this year than the strategic shift they represent: "George Bush put forth more of an effort in the churches this year."
