She knew when to say "yes," when to say "no," and mostly when to say "I don't recall." Since she asked for questions to be rephrased so often tells me that she was shopping for certain phrases that she had been coached on.
As for the other side, again my opinion - it looked like they were not prepared. The lawyer for the plaintiff shuffled through papers too much, was unclear on what video clips were what, and they had not arranged for simple laptop to screen visuals that anyone who cracked open a PowerPoint for Dummies book could have done smoothly.
Added to that, knowing that rethugs dismiss any news outlet outside of Fox News, OAN, and NewsMax as "fake news," they should have used clips of her speaking the words she claimed were taken out of context without letting it slip that the source was Mother Jones. Would anyone here accept a video sourced from a reichwing source as a serious piece of evidence in a court proceeding? Of course not.
