She talked more about Trump than herself.

Throughout her campaign and the CNN town hall, Harris repeatedly promised that her administration would break away from the "hate" and "divisiveness" that supposedly characterize President Trump and his campaign. But despite these promises, it seemed like Harris's answer to every question was to bash Trump. From questions about how she would support or not support Israel to questions about potential Supreme Court reforms, the answer was the same: Orange Man Bad.

Even the CNN after-show panel complained that she spent far too much time talking about Trump. Her performance lacked substance and proved that her campaign isnot about anything she has to offer the American people, it's solely about hating Donald Trump.

She missed the opportunity to further define herself.

Harris spent so much time Trump-bashing that she never got into any detail about her policies. This was an event designed to give her the chance to lay out her platform and define who she is as a candidate and she utterly failed to do so. As mentioned before, all she really spoke about was Trump, a candidate who almost every voter is highly familiar with. This was a critical failure on Harris's part, she missed possibly one of, if not the last chance to make an impression on voters before the election and according to recent polls, this was a chance she could not afford to miss.

She gave several radical and dangerous remarks.

The few times Harris managed to reveal some of her policy ideas it became clear why she was being so coy: they are blatantly dangerous. In between her anti-Trump tirades where she makes Trump out to be the biggest threat to the Constitution the country has ever seen, Harris let slip that she is open to Supreme Court reforms, including adding more Justices to the bench. This is known as court-packing and is most certainly unconstitutional, as well as one of the hallmarks of an authoritarian takeover, as Glenn has pointed out.

Harris also spent the first several minutes of the event making dangerous accusations against Trump, calling him a fascist and comparing him to Adolf Hitler. She would echo this sentiment the following day in a surprise address. Glenn explained on his radio show just how dangerous and inciteful this kind of language is and the kind of damage it can do. This looks like a desperate, last-ditch attempt to sway people away from Trump during this critical time of the election cycle.
