Editor’s note: Welcome to the inaugural edition of the 2020 Vision, a weekly look what’s happening in New Hampshire’s first-in-the-nation presidential primary, as well as other campaign and political news that impacts the Seacoast region.

Democrat Julian Castro will be in Somersworth on Tuesday, just three days after formally declaring his candidacy for president.

The former San Antonio mayor and U.S. Housing and Urban Development secretary during President Barack Obama’s second term is scheduled to meet with the Tri-City New Hampshire Young Democrats on Tuesday evening in Somersworth, Seacoastonline learned.

Castro declared his candidacy for president on Saturday, in his hometown of San Antonio. He’ll be heading to the first-in-the-nation primary state from Puerto Rico, where he had a full day of events planned for Monday.

His event at Teatotaller in downtown Somersworth kicks off a busy schedule. On Wednesday morning, he’ll headline "Politics and Eggs" at the New Hampshire Institute of Politics at Saint Anselm College. The speaking series is a must stop for White House hopefuls. Castro’s campaign says they’ll hold multiple events throughout the state throughout Wednesday.

Castro made three trips to New Hampshire last year, making friends and building connections with the Democratic activist class.

Warren opens up on opioid crisis

Sen. Elizabeth Warren says when it comes to the opioid epidemic, “I’ve already put my money where my mouth is.”

The Massachusetts Democrat and White House hopeful detailed her efforts to battle the drug crisis in an interview with Seacoastonline before her event at Manchester Community College on Saturday. Warren’s trip to New Hampshire was her first since announcing a presidential exploratory committee two weeks ago.

“We’ve got to make sure the resources are there,” Warren implored. ”That there are enough beds, enough therapists, enough support groups. Enough to help people. This is what we do together. We have to battle back against this crisis.”

The senator highlighted that she and Rep. Elijah Cummings of Maryland “have put together a 10-year proposal to put the kind of resources into this problem that the doctors, the scientists, the public health officials tell us that is what’s really needed here. We’ve introduced it in the House and the Senate. I’d like to see it become law.”

Swalwell returning to Seacoast

Congressman Eric Swalwell of California will be in New Hampshire late this month.

The 38-year old potential Democratic presidential contender and member of the U.S. House Intelligence Committee will headline a meet and greet with the Rockingham County Democrats. The gathering is scheduled for 7 p.m. Jan. 31 at the Exeter Inn in — where else? — Exeter. The event is free and open to the public.

“We look forward to hearing Congressman Swalwell’s views on the key issues of the day,” Rockingham Democrats chair Larry Drake said. “I am sure the discussion will be very thought-provoking.

The visit will be Swalwell’s third to New Hampshire since early November. During that trip, the congressman headlined a gathering of Democratic activists at state Sen. Martha Fuller Clark’s Portsmouth home.

Pappas comes to Exeter for first town hall

Freshman Rep. Chris Pappas on Sunday held his first town hall since he was sworn in less than two weeks ago to the U.S. House of Representatives. And the Democrat who represents New Hampshire’ First Congressional District held the gathering in Exeter – birthplace of the Republican Party.

“What better place to hold my first town hall meeting than the historic Exeter Town Hall,” Pappas told Seacoastonline.

Pappas made numerous stops in Exeter last year, during his campaign to succeed retiring Democratic Congresswoman Carol Shea-Porter.

But Pappas isn’t playing favorites with the Seacoast region. A week ago the former three-term executive councilor and co-owner of the family owned Puritan Backroom restaurant held a ceremonial swearing in Manchester, where he grew up and lives.

“During my first weeks in office, I will be making myself available to constituents in each region I represent to hear their thoughts and concerns so I can best represent them in Washington,” Pappas explained.

New Hampshire’s First Congressional District stretches from the greater Manchester area east to the Seacoast and north to the Lakes region and North Conway. It includes all of Strafford and Carroll counties, and nearly all of Belknap and Rockingham counties.
