I'm not sure it will open their eyes completely, but what I can say is it will demoralize them so much they don't vote.  Trump's presidency has been a non-stop protest with all their eggs on impeaching via Mueller investigation.  To the point that every day that investigation is closed and Trump remains will weigh on them.  Sure some will switch to campaign fever, but many will just burn out.  They'll watch netflix on election day and say the Democrats wasted everything trying to take down Trump. And what is going to really eat at them is if someone points out Hillary endorsed Trump.  Her campaign pushed for Trump to win the nomination to try and give her an easy victory.  This is verifiable in her campaign emails.
