<h1>Libertarian president's party wins decisive midterms, gains congressional majority to sustain vetoes and push tax, labor reforms</h1> The libertarian president's party won decisive midterm victories, capturing over 40% of the vote, large gains in the lower house and additional Senate seats, securing a congressional majority sufficient to sustain vetoes, block impeachment and advance ambitious tax and labor reforms. Results exceeded expectations while the main populist opposition recorded its weakest showing in years. The outcome follows substantial financial backing from the U.S. administration and came amid low turnout, recent market turmoil, austerity measures that cut inflation sharply but raised unemployment and living costs, and bribery allegations against a close family member that had dented the president's anti-corruption image.
