With just two weeks until the presidential election the race for the White House is still remarkably close.

Recent polls show President Barack Obama and his Republican rival, Mitt Romney, in a neck-and-neck race.

Now, the integrity of electronic voting machines is back in the spotlight. Reports are circulating there are “dubious links” between the voting machines in some counties (Hamilton and William) in Ohio and Governor Romney.

The machines are supplied by Hart Intercivic, a national e-voting company. The Austin-based firm is partially owned by H.I.G Capital, an investment company that has business ties to Solamere Capital, Tagg Romney’s (Mitt’s oldest son) equity firm.

The suggestion is that the Romney link is at best a conflict of interest, with even the potential for bias, fraud or irregularity.
