Former South Carolina Governor and Congressman Mark Sanford has declared his candidacy for the U.S. Senate, stepping into a competitive field for the special election following Senator Lindsey Graham's passing. Sanford, known for his fiscal conservatism and previous presidential bid, emphasized the urgency of national financial issues as his primary motivation.

“We're at a tipping point, and that's why I've decided to run for the U.S. Senate,” Sanford announced in a video launch. He urged voters to consider his past efforts in safeguarding economic futures during his terms in Congress and as governor. This move marks Sanford's re-entry into a political fray dominated by notable figures including Senator Darline Graham, Representatives Russell Fry and Ralph Norman, and businessman Mark Lynch. The late senator's sister, Darline Graham, has already secured an endorsement from former President Donald Trump.

Sanford's political career has been both highlighted and marred by his staunch fiscal advocacy and personal controversies, notably an extramarital affair during his governorship and his outspoken criticism of Donald Trump, which included challenging Trump in the 2020 presidential primaries.

The primary election, scheduled for August 11, will determine the Republican nominee who will vie for a full six-year term in the Senate. Sanford's political journey includes initial election to Congress alongside Lindsey Graham in 1994, followed by his governorship beginning in 2002 and a return to the House in a 2013 special election. After a brief stint last cycle aiming to reclaim his Congressional seat, Sanford pivoted to focus on a debt-focused nonprofit before announcing his Senate bid.

Highlighting the peril of the national debt, Sanford voiced deep concerns about the economic implications for future generations. “I'm worried for our children because for the first time, America is borrowing from the future faster than we're building it,” he stated. He warned that unchecked debt could "crush our economy, wipe out our savings, and could even destroy our republic."

Sanford's entry adds a seasoned, albeit controversial, voice to a crowded and dynamic race, setting the stage for a fiercely contested primary in South Carolina.
