The Miami Herald: Within 2½ weeks, 2,552 online requests arrived from voters who had
not applied for absentee ballots. They streamed in much too quickly for
real people to be filling them out. They originated from only a handful
of Internet Protocol addresses. And they were not random.  It had
all the appearances of a political dirty trick, a high-tech effort by an
unknown hacker to sway three key Aug. 14 primary elections, a Miami
Herald investigation has found.  The plot failed. The elections department’s software flagged the requests as suspicious. The ballots weren’t sent out.  But who was behind it? And next time, would a more skilled hacker be able to rig an election?

Six
months and a grand-jury probe later, there still are few answers about
the phantom requests, which targeted Democratic voters in a
congressional district and Republican voters in two Florida House
districts.  The foreman of that grand jury, whose report made
public the existence of the phantom requests, said jurors were eager to
learn if a candidate or political consultant had succeeded in
manipulating the voting system. But they didn’t get any answers. “We were like, ‘Why didn’t anyone do something about it?’ ” foreman Jeffrey Pankey said.
