(CNN) - Gov. Bill Richardson, D-New Mexico, said the U.S. needs to have a paper trail from the voting machines on election day.
"My state was one of those... that because of the touch tones there was uncertainty about the elections," Richardson said.
He says the paper trail would not only fix the problem of uncertainty but it would help improve low voter turnout.
"We have close to 50% of those Americans eligible to vote voting. That is inexcusable compared to many other nations. We need to have same-day registration."
Richardson also took aim at the GOP. "We need to have an effort to get the Republican party to stop suppressing minority voters."
