Retiring Republican Sen. Thom Tillis of North Carolina hosted his annual dog parade on Capitol Hill this week, drawing dozens of lawmakers and their canine companions to the event marking his final year in office.
The tradition, now in its seventh year, has become one of the lighter moments on the congressional calendar. Tillis, who announced he would not seek reelection in 2026, has used the event to showcase a side of himself that differs from typical partisan politics — a trait that has defined his tenure in the Senate.
What the Left Is Saying
Progressive Democrats and liberal advocacy groups have noted Tillis's occasional breaks from party orthodoxy, particularly his criticism of former President Donald Trump. Some progressive activists have acknowledged that Tillis's willingness to part from GOP leadership on certain issues distinguishes him from many colleagues.
Senator Elizabeth Warren of Massachusetts has been among those who have acknowledged bipartisan moments when working with Tillis on legislation affecting military families and veterans' issues. Progressive commentators have also pointed to Tillis's votes against some of Trump's judicial nominees as evidence of his independent streak.
However, liberal critics note that Tillis has largely aligned with Republican positions on most policy priorities, including voting records on budget matters and regulatory changes. Some progressive voices have characterized the dog parade as a public relations effort that contrasts with his voting record.
What the Right Is Saying
Conservative Republicans have largely supported Tillis throughout his two terms in the Senate, though his occasional independence on Trump-related matters has drawn mixed reactions from the party's base. Many Republican lawmakers participated in this year's dog parade, demonstrating continued collegiality within the conference.
House Republican leaders have praised Tillis for his work on judicial confirmations and national security matters. Conservative commentators note that while Tillis has occasionally broken with Trump, he has remained a reliable vote on core Republican priorities including tax policy and government spending.
Some conservative media figures have criticized Tillis's Trump criticism as inconsistent, arguing that his positions have shifted over time. The senatorial dog's day event has drawn bipartisan participation, with Republicans and Democrats alike turning out to celebrate the tradition.
What the Numbers Show
Tillis was first elected to the Senate in 2014, defeating incumbent Democrat Kay Hagan in a closely watched race. He was reelected in 2020, defeating Democrat Cal Cunningham. His two terms represent eight years of service.
During his tenure, Tillis has voted with Senate Republican leadership approximately 90% of the time on key votes, according to congressional tracking data. He has served on the Armed Services Committee, Judiciary Committee, and Veterans' Affairs Committee.
Tillis announced his retirement in early 2026, saying he wanted to pursue opportunities outside elected office. He will leave the Senate at the end of the current term, with a competitive race expected to fill his seat.
The dog parade tradition began in 2019 and has grown each year, with this year's event featuring the largest turnout since its inception according to congressional staff.
The Bottom Line
The annual dog parade represents one of Congress's more lighthearted traditions, and Tillis's final hosting of the event comes as he concludes a Senate career marked by both party loyalty and occasional independence. His decision to retire opens a competitive seat in North Carolina, a state that has become increasingly competitive in federal elections.
The event drew bipartisan participation, reflecting the unusual collegiality that can emerge even in a polarized institution. Tillis's legacy will likely be defined by his committee work and his occasional breaks from party lines, particularly regarding the former president. What happens next in North Carolina's Senate race will be closely watched as both parties vie for the open seat.
