Brazilian President Luiz Inacio Lula da Silva's chosen candidate to succeed him next year came out on top in elections Sunday, but fell unexpectedly short of an outright win needed to avoid a runoff. The official complete tally showed Dilma Rousseff, Lula's former cabinet chief, won 47 percent of the vote to 33 percent for her nearest rival, former Sao Paulo state governor Jose Serra. That was short of the 50-percent-plus-one-ballot threshold Rousseff required to obviate an October 31 knockout round against Serra -- a round all pre-election surveys said Rousseff should have been able to avoid.
