I suspect this will go about as well as impeaching Clinton did, but for substantially less cause. It's going to inevitably throw a spotlight on Biden's family corruption (ironically, because the whistleblower bruhaha may have been intended to protect Biden). Ultimately, though, Biden has real and admitted exposure to a legitimate corruption investigation in the Ukraine. Trump's exposure is unknown, but likely to be lower, considering he doesn't seem afraid of releasing transcripts and even the whistleblower's claims appear weak and based on inaccurate hearsay.
My gut feeling is that this is a desperation move. It's not really about the "whistleblower". It's about painting the investigation into Biden's family corruption as a partisan abuse of authority similar to what Clinton and Obama conducted against Trump. It's necessary in the same way that Clinton had to "dirty up" Trump with Russian Collusion Dirty Hacking Tricks after she was caught using a private email server to collude with Russians and hide her emails.
