Wired reports that voting machine company HartInterCivic filed an antitrust lawsuit against two other voting machine companies, Diebold and Election Systems & Software.  The suit also notes Sen. Schumer’s interest in the issues involved in the lawsuit, which seem to coincide with the plaintiff’s interest.

Schumer, a New York Democrat, agreed with Hart InterCivic’s assessment of the sale.

“If this acquisition proceeds, one company could control over three-quarters of the U.S. market for voting systems,” Schumer wrote in a letter to Attorney General Eric Holder. “Given other factors, including high barriers to entering the market, I am deeply concerned that local governments and taxpayers will not be getting a fair deal because too much market power will be held in too few hands.”

Schumer also noted that consolidating the election-machine market in fewer hands would make it easier for someone to commit fraud.
