Indiana Senate, District 1

Indiana Senate. 4-year term. Open seat: Dan Dernulc is not on the ballot.

What this office does

Members of the Indiana Senate write and vote on state laws as part of the Indiana General Assembly. The Senate has 50 members, each representing one district for a four-year term; about half the seats are elected every two years [1].

The job in full — the duties the Indiana Code puts in it, the term, what it pays and who sets that, and what to ask a candidate.

What the law puts in this job (2)
  • Introduces and votes on state legislation as one of the two chambers of the Indiana General Assembly [1].
  • Must be at least 25 years old when taking office and have lived in the district for at least a year, under Article 4 of the Indiana Constitution [1].

About this race

  • Senate District 1 covers part of Lake County; the Senate Republican caucus's news items for the district mention Highland, Schererville, St. John, Hammond and Dyer [3].
  • This is an open seat: incumbent Dan Dernulc lost the May 5, 2026 Republican primary to Trevor De Vries, 75.1% to 23.3%, with Nader Liddawi at 1.6% [5]. Ahead of the primary, both President Donald Trump and Gov. Mike Braun endorsed De Vries over Dernulc, part of their endorsements against Senate Republicans who had opposed the December 2025 redistricting bill [10].
  • Scott Houldieson was unopposed in the Democratic primary [11].
  • No general-election debate or candidate forum for this race was found as of October 10, 2026.
  • Both candidates list utility costs as a priority: De Vries's campaign site opposes NIPSCO's monopoly and supports energy choice, while Houldieson's site calls for oversight of regulatory agencies [12, 13]. They differ on labor policy; Houldieson supports repealing Indiana's right-to-work law and restoring prevailing wage, while De Vries emphasizes cutting income and property taxes and government spending [13, 12].
