PLEASANT CORNER, Pa. – On a clear day, a hiker standing atop Bake Oven Knob, a high point along the Appalachian Trail in Lehigh Furnace, Pa., can see most of state Sen. Jarrett Coleman’s district.

Below the crest of Blue Mountain lies a patchwork of woods and farmsteads in the historically Pennsylvania Dutch communities. On the horizon lies the growing, diverse footprint of Allentown, Pennsylvania’s third-largest city.

Beyond Allentown lies mixed suburbs like Emmaus and Coopersburg, before again giving way to rural communities like Hosensack and Old Zionsville, the latter being the hometown of former three-term Republican Sen. Pat Toomey.

As Pennsylvania’s friendlier economic climate draws transplants from New York and New Jersey, its farmland has been gradually replaced by residential subdivisions and corporate warehousing.

INSIDE DEMOCRATS’ GROUND GAME IN PENNSYLVANIA’S ‘SWING’ LEHIGH VALLEY AREA

All of those factors combine to create what Allentown Democratic Mayor Matt Tuerk called the “swingiest” area of the perennial bellwether state.

Coleman, a Republican and an airline pilot who entered the political scene as an outspoken conservative member of the Parkland School Board during the height of national controversies, said Republicans are poised to do well in the Lehigh Valley this year.

“We are seeing some of the highest levels of excitement and motivation from folks in the Lehigh Valley. I am hopeful for turnout to exceed 2020 levels,” Coleman said. The GOP underperformed that year in both Lehigh and Northampton counties.

“Although Lehigh County contains a ‘blue’ urban core, life for everyone, regardless of political party, has gotten harder under the current administration. This is prompting even some who have traditionally voted Democrat to cast ballots for GOP candidates.

“The economy, border and community safety remain top concerns for those in the Lehigh Valley.”

Democrats are also aiming to retake the Pennsylvania state Senate, and state Sen. Sharif Street, D-Philadelphia, the state party chairman, said in a recent interview the landmark achievement is within reach.

But, in terms of Harrisburg and Washington, Coleman said, “kitchen table issues” are front of mind in his district, which also includes a slice of the Philadelphia “swing” suburb of Bucks County, and will help the GOP at both levels.

“It’s very clear that the majority of Pennsylvanians — and especially those in the Lehigh Valley — are far worse off than they were four years ago. The GOP has a platform with specific steps to take to improve the lives of those in the Lehigh Valley, Pennsylvania and across the nation.”

Democratic “demonizing” of Trump has not helped his constituents’ pocketbook or public safety via the open border, he added.

Off the side of Bake Oven Knob, adjoining the county lake now named for him, lies the property of Revolution-era farmer Frederick Leaser.

As the British approached Philadelphia in 1777, Leaser loaded the Liberty Bell onto his wagon during one of his trips to take produce to market and hauled it home to Lehigh County, preventing the Redcoats from melting it down for ammunition.

Such patriotic, community sentiment remains in that part of the valley, with American flags flying in yards during holidays and local churches and fire halls hosting community dinners, from the Jacksonville oyster supper to the German Groundhog Day spread at the local Grundsau Lodsch.

A few blocks west of the church where Leaser ultimately hid the bell is the headquarters of the Lehigh County Republican Committee.

Chairman Joe Vichot said the party’s presence is ubiquitous at many local events, including the Schnecksville Fair and Allentown Puerto Rican Day Parade.

Trump rallied at Schnecksville’s fairgrounds earlier this year, claiming how crucial the area is this cycle.

“We have literature on candidates, and we listen and speak to residents about the issues,” Vichot said, adding his party’s float won third place in the aforementioned parade and that more than a dozen attendees were registered to vote in only a few hours. 

The party also registers voters and has made connections with civic leaders in the Jewish, Syrian and Muslim communities, he said.

“The top two issues we hear are the border and the economy,” Vichot said.

“[Voters] want a new direction. They don’t believe the open border policies of Biden/Harris is good for their wallet or safe for their family.”

In neighboring Northampton County, home to Bethlehem, Easton and smaller cities like Nazareth and Wind Gap, conservatives are similarly pounding the pavement to get their messages out.

“Our local party is very involved. We are able to communicate with our voters. We are able to text them, call them, and they are receptive to our requests to … help out in going door to door and making phone calls for us,” Northampton County Republican Committee board member Andrew Azan III said.

Azan told Fox News Digital there’s a “waitlist” for Trump-Vance signs in his county, which the Republican nominee flipped red in 2016 but lost in 2020.

“That’s a positive sign,” he quipped.

With Bethlehem and Easton’s population of retired steelworkers giving way to new Hispanic and African American residents, the party has adjusted its messaging, but not its principles, to meet the changing diversity of the Lehigh Valley where it stands, Azan added.

In that regard, according to Lehigh Valley Tea Party board member Tom Carroll, locals are more receptive to the conservative platform, and the right wing is “more unified than I’ve ever seen.”

“They are more concerned than ever about losing their country because of the Marxist and socialist policies that are coming out of both Biden and, of course, now Kamala Harris,” said Carroll, whose Tea Party group is the nation’s largest, with 7,000 recorded members.

“She’s going to open the borders, and she’s going to enact the tax policies that she’s talked about, things like [levying] unrealized capital gains. Our voters are educated, and they’re concerned because they know what that will do to the economy.”

Carroll, an attorney who also helps lead the Bethlehem City GOP, said he’s been involved in politics since the 2010 midterms and recognized Republicans typically lagged behind Democrats in that realm most cycles.

“But there has been such a reach-out to the voters … in Pennsylvania in that there’s a lot of grassroots knocking on doors and meeting people and having a lot of events and surrogates from the various campaigns coming in.

“We believe in President Trump. We want him to get elected. And we realize Pennsylvania is the most important state in the nation.”
