The Dems are going to need some incontrovertible proof that Trump was holding up aid unless/until Ukraine agrees to investigate Biden specifically. Inference and insinuation from Democrats aren't going to make a compelling case. In today's hearing, Schiff was acting out a mafia mob-boss scenario where Trump was supposedly pressuring Zelenskyy to do him favors, but he was using his own subjective and jaded interpretation of the call transcript, and using his own words, to do it. He was departing from the call transcript, and many people were rolling their eyes.
The Dems are asking people to read the phone transcript and infer that pressure from Trump was implied throughout the course of the phone call. They keep quoting the phrase that mentions Biden later in the call and keep saying, "See, this implies that Trump was pressuring..." They keep using the word "imply." However, if you want to impeach a sitting president, there is a significant burden of proof, and you need something more than a subjective read of a phone call (or an anonymous whistle-blower's subjective read of a phone call that s/he didn't participate in).
A lot of people are describing this as a very normal phone call between two world leaders, one that Trump could have simply withheld and protected with executive privilege. The fact that Trump has released the call transcript and the whistle-blower complaint (not just to Congress, but to the public), without using executive privilege, should tell you that he wants this out there and that he wants this to blow up.
In the words of Paul Simon: "A man hears what he wants to hear, and disregards the rest..."
