Chamber of Deputies Senate
If no single candidate gets a majority of both the Chamber and the Senate, a second round is then called for. At this stage, a candidate requires an absolute majority of merely those present at the time of voting in both the Chamber of Deputies and the Senate. The number of votes required in the second round might be the same as in the first round but, as in 2008, can be a little less due to the absence of a few parliamentarians. In this second round, a single candidate would still need to win a majority in both the Chamber and the Senate.
