Was the 2004 US election stolen?

Rolling Stone magazine appear to have just accused the Republican party of stealing the 2004 presidential election. This is their subtitle:

Republicans prevented more than 350,000 voters in Ohio from casting ballots or having their votes counted — enough to have put John Kerry in the White House.

Isn’t Rolling Stone a fairly prestigious magazine, journalism-wise? Blimey. I haven’t read it yet – it’s best printed out, I think – but I’m looking forward to it!
