Michel Barnier unsuccessfully tried to win over Marine Le Pen until the last moment.
Barnier prioritized the far-right party, Rassemblement national, above others.
Barnier also tried to strategically appease RN.
By pandering to the far-right by giving into their demands, Barnier failed both morally and strategically.
Lastly, Barnier has diminished the influence of the republican right following his attempts to appease RN.
Conclusion: Barnier's strategy for dealing with the far-right, primarily by trying to appease RN to ensure his political survival, was not only morally questionable but strategically ineffective, diminishing the influence of the republican right.
