NASA co-principal Musalia Mudavadi has said the IEBC is to blame for the chaos in the country.
He told the BBC on Friday that the commission's decision to force the repeat elections on people was wrong.
"You cannot have police all over the place and tell people to go and vote. That is intimidation," Musalia said an interview on Focus on Africa.
The opposition called for electoral reforms before Thursday election following the nullification of the August 8 presidential vote.
NASA leader Raila Odinga withdraw from the race citing IEBC's lack of preparedness to deliver a free, fair, and credible election.
This was after IEBC chair Wafula Chebukati said that commission cannot hold free and fair elections because it was divided.
"This is double speak because the IEBC itself told us that it cannot hold a credible election. The commission itself has created a crisis," Mudavadi said.
Musalia said that the awaited announcement to its supporters on what products was not to be viewed as unrealistic.
"We all feel the pinch as well but the IEBC is the problem.
Had the elections been free and fair this would not have taken place."
