 In 2007, Bachelet announced that any cabinet members seeking to run in the upcoming elections would have to announce their resignation by January, 2008.With the popularity of the Bachelet administration at a low, and the Concertación's support suffering, Lagos Weber announced his resignation on December 6, 2007, to make his candidacy for the Senate of Chile for the district of the Valparaíso Region in the December 2008 election.Seen as a rising star, often aided by his recognizability as the former president's son and a visible spokesman to the current president, the upcoming election takes on increased importance as the Concertación faces the risk of losing its dominant role in the government.
