The main thing to keep in mind is not what it says, but where it comes from: the most lawless, secretive, and dishonest administration in U.S. history. As such, the accuracy of its contents is not to be trusted.
Alas, the media seems to be taking the whole thing much more at face value than it deserves. I will note that it is very early in the process (the alleged transcript was released only this morning), but this is still disturbing, as it amounts to intentionally inaccurate reporting in a way that benefits the Trump regime.
Given that the odds strongly favor the transcript being deliberately crafted to make the administration look good, anything it contains that does not make it look good should be taken as particularly damning, because it means that despite the Trump regime’s efforts to whitewash it, it is still clear that impeachable conduct occurred.
Whatever the transcript says, odds favor what was actually said was even worse.
