I hope Pence said that because it’s what he HAD to say.
I wish Pence had said something along the lines of, we will accept the results of a free and fair election. I would not want to preclude actions afterwards, if clear evidence of vote fraud turns up.
We have seen in recent years, some high profile recounts and legal actions by the Democrats, such as Florida 2000, and Minnesota 2008 in the Al Franken election. We see how well the Democrats accept results of close elections. So we should always keep options open. We want to ensure that our elections are conducted properly.
