I disagree. We can walk and chew gum at the same time.
I think he'll be impeached. But he won't be convicted. And that's ok. What is NOT ok is for the House to neglect to fulfill its obligations as the rightful place for Executive/presidential oversight.
And for sake of future generations, that's what needs to happen. There is no harm in losing the conviction vote in the Senate. The trial will allow every single Trump transgression to be documented on live t.v. And the votes of every Republican Senator will be recorded for history and used against them in states like existing (or soon-to-be) swing states (like Maine, Arizona, Colorado, Texas, Georgia, Florida, Pennsylvania, Wisconsin, North Carolina, Nevada, etc.) where Trump's approval and/or re-elect numbers are already underwater.
If this president never faces impeachment by the House, there will likely NEVER be sufficient grounds to impeach another president again. And that cannot happen. We might as well just rip up the first 3 Articles of the Constitution (i.e. Separation of Powers), and prepare ourselves for an autocratic dictatorship.
