Alfonso Lopez Michelsen vs Macky Sall

López Michelsen enacted a comprehensive tax reform that simplified the tax system, broadened the tax base, and increased government revenue. The reform aimed to reduce fiscal deficits and improve public finances.

Alfonso López Michelsen became President of Colombia in 1974 as the first elected under competitive elections after the National Front. His administration faced severe economic challenges including inflation and fiscal deficits.

López Michelsen implemented austerity measures including devaluation, spending cuts, and tax increases to address a balance of payments crisis. The measures stabilized the economy but caused social unrest and reduced his popularity.

López Michelsen established Colciencias, the national science and technology institute, to promote research and innovation. The institution became a key driver of scientific development in Colombia.

Macky Sall won the presidential election in a runoff against incumbent Abdoulaye Wade. His victory was seen as a defense of democratic norms after Wade's controversial third-term bid.

Sall launched the Plan Senegal Emergent, a national development strategy focusing on infrastructure, agriculture, and energy. The plan aimed to achieve middle-income status by 2035.

Sall oversaw a constitutional referendum that reduced the presidential term from seven to five years and limited the president to two terms. The reform was intended to strengthen democratic institutions.

Sall was re-elected in the first round with 58.3% of the vote. The election was peaceful but criticized by opposition for excluding some candidates, though international observers noted improvements.
