There are plenty of theories about the Democrats’ “real” end game in the impeachment proceedings: turning voters off on Trump, turning voters off on Republican senators; highlighting the swampiness of the President’s team. It could be all of these. But there is other objective that might be in play.

At the end of the day, Chief Justice Roberts could be their real target. Sometime soon the Supreme Court is going to have to decide on how big of a stone wall Donald Trump can erect. So far, Trump has gotten away with ignoring all requests for information from Congress and state prosecutors.

The Democrats may be trying to show Roberts what happens when the President is allowed to get away with stonewalling. He becomes untouchable. Roberts is a conservative, but he is a constitutional conservative, not a partisan conservative. Team Trump’s efforts to rise above the law might just rub him the wrong way and backfire on them.
