They have about 6 minutes each. Not a lot of time, and easy for Hillary to evade the questions for six minutes with her deceitful posturing, until the next Senator's turn came up.
If 8 or 10 of them had planned their questions together in advance and worked together to make the complicated case against her (a task that alone would exceed 12 minutes, let alone the 6 given per Senator) then perhaps they could have pinned Frau Hillary down.
But they didn't, and I think that played well for Hillary to the politically uninformed. Despite that they were right, and Hillary was evading the truth, that better interrogation would have not allowed her to hide.
