The central challenge for France's next generation of leaders may therefore be not simply to develop compelling policies, but to restore citizens' sense that political institutions are responsive to their lives.
His emergence comes as traditional parties struggle to mobilize voters and the political center remains deeply fragmented.
The deeper issue, however, is not whether Riner can win.
What his potential candidacy reveals is the weakness of France's traditional political alternatives and a growing demand for leaders whose personal histories, values and commitments resonate with citizens.
Seen in that light, Riner's rise is less an isolated celebrity phenomenon than a symptom of a changing relationship between political authority, public trust and democratic participation.
It points to a broader shift in democratic competition: the growing weight of personal credibility, public visibility and the capacity to embody an alternative to established political elites.
"It's the ability to capture attention,"Paulson said.
Yet visibility alone does not confer political credibility.
Riner's public commitments against racism and xenophobia may resonate with voters, Paulson said, but he questioned whether the champion has articulated a sufficiently developed political vision to become a serious presidential contender.
"Voters vote for people they sense will stand up for them,"Paulson said, linking that demand for identification to a wider crisis of democratic representation.
Paulson concluded that the real political opportunity lies in reimagining governance itself: bringing decision-making closer to citizens and giving them a more meaningful voice in the democratic process.
