WASHINGTON - Former U.S. Senator Thom Tillis has issued a stark warning to his Republican colleagues about the potential consequences of supporting the proposed "Great America Act," cautioning that the legislation could trigger significant electoral backlash by undermining healthcare commitments to voters.

The North Carolina Republican, who recently announced his retirement, cited analyses from three independent groups - including bipartisan policy experts and a nonpartisan hospital association - showing the bill would result in at least $26 billion in healthcare funding cuts, even under the most optimistic projections.

"This is precisely the kind of broken promise that handed Democrats historic midterm losses in the past," Tillis said in his statement. "The Republican Party appears to be repeating those same mistakes, and we will pay the price at the ballot box."

The former senator drew parallels to the 2010 Affordable Care Act debates, when Democratic healthcare policy reversals contributed to the party losing 63 House seats. Tillis argued the current legislation represents an even more dramatic departure from Republican campaign trail promises about protecting healthcare access.

North Carolina as Warning Sign

Using his home state as a case study, Tillis highlighted how the proposed cuts would disproportionately affect rural hospitals and Medicare Advantage plans popular with senior citizens - a key Republican voting bloc. The nonpartisan North Carolina Healthcare Association projected the state alone would lose $3.2 billion in federal health funding over the next decade.

Political analysts note the warning carries particular weight coming from Tillis, who built his reputation as a pragmatic conservative willing to break with party leadership on healthcare issues. His retirement announcement last month had already sparked speculation about growing divisions within the GOP on domestic policy.

The White House has dismissed Tillis's concerns, with press secretary Karine Jean-Pierre calling them "misguided" during Tuesday's briefing. However, at least five House Republicans have reportedly expressed reservations about the bill's healthcare provisions following the former senator's intervention.

As the debate continues, observers suggest Tillis's warning may signal broader discontent among establishment Republicans about the party's policy direction in what promises to be a contentious election year.
