The Catalyst
Tillis’ decision to not seek reelection was influenced by his recent vote against Trump’s tax and spending bill. Tillis argued that the bill would harm North Carolina, particularly its hospitals and rural communities, and could force the state to make “painful decisions like eliminating Medicaid coverage for hundreds of thousands who recently received it.”
President Trump criticized Tillis for his vote, calling it a “big mistake” and indicating he would meet with Republicans who want to primary Tillis.
Inside Forces
Tillis expressed his dissatisfaction with the political environment, stating that he hasn’t been excited about running for another term. He emphasized the choice between navigating “political theatre and partisan gridlock” in Washington or spending time with his family.
Tillis plans to focus on producing meaningful results without the distraction of fundraising or campaigning during his remaining 18 months in office.
