You have to give credit to congressional Democrats for one thing: They are an extremely hopeful bunch. After years of Russia investigations aimed at toppling Donald Trump, they came away with what Grandmother would have called “bupkis.” But, not daunted, they quickly latched onto a whistleblower report about a phone call with Ukraine, and launched an up tempo effort, one last-ditch attempt to take the president down.
The result of this exertion did include a vote to impeach Trump, but did not attract a single GOP vote. This is also almost certain to the result in the senate trial as well. But wait! Now former National Security Adviser John Bolton has agreed to testify if called, and the Democrats are racing toward Lucy again, confident this time she won’t move the football.
The excitement from Democrats comes from the fact that Bolton in the past few months has sent a few mysterious tweets and said through lawyers that he does have information that did not come up in impeachment. Bolton may well have new information, but the idea that he is going walk into the Senate chamber if subpoenaed with a smoking gun is pure wish casting.
The crux of the dispute between Democrats and Republicans over the Trump administration’s action to delay funding to Ukraine is not over whether it happened, but whether the president was acting within his authority. It is almost inconceivable that Bolton could provide any evidence that would change that basic dynamic.
