As far as proving he engaged in impeachable offenses, yes.  As far as moving towards experiencing any sort of direct consequence for that, no.  At this point, only a small majority of the American people (and almost no Republicans) believe that what he did was an impeachable offense.  Unless more people become convinced of that, then nothing is going to come of all this.  Republican congresspeople will simply continue to either profess Trump's innocence (despite the facts) or say that what he did isn't that big a deal.  And the Senate will vote for acquittal.

Republican held legislatures in such states as, say, Michigan, Pennsylvania, and Wisconsin could easily say the electoral votes go to Trump even if the majority of the people voted for the Dem candidate.  The Governors (who are all Democrats in those states) have zero say in the matter.

Now then, it probably be political suicide for them to do that and, of course, there would be numerous lawsuits filed, BUT, unfortunately, there is precedence....  Bush v. Gore.  The Supreme Court wrote:    “There are a few exceptional cases in which the Constitution imposes a duty or confers a power on a particular branch of a State’s government. This is one of them.”  By using that "logic", I can easily see a number of states' legislatures gearing up.

So Trump definitely needs to be impeached and tossed from office.  Otherwise, the 2020 elections will probably turn into a bloodbath.

It's a shame the 1800 debacle led to ticketed election of the president and vice president, because as originally conceived, impeachment and removal from office would have elevated the electoral runner-up to the presidency. The 12th Amendment neutered impeachment by keeping in place the same corrupt administration.

(I've read contemporaneous debates on the then-proposed amendment from Congress and several state legislatures, and so far haven't found any evidence the consequences for impeachment were raised by anybody; legislators were primarily concerned with avoiding the agony of another protracted Electoral College deadlock.)
