Personally, I don't like to trust commentary on FiveThirtyEight's tracker from anyone other than FiveThirtyEight. They do a fantastic job of tempering expectations and not putting too much stock in momentary changes in the tracker. The current numbers are basically the same as they were on May 11:
It hasn't changed much, even after all the wild shiz that has happened since May 11. Furthermore, the polls usually work on a delay, so they haven't yet factored in the assassination attempt, or the RNC. And often, the tracker stays at a dead-even heat largely because their statistical model factors in uncertainty from the 4 months between now and Election Day.
All of that is to say: the race is still essentially dead-even. Like Chris said in the OP, the most important thing to do is vote and encourage others to vote, no matter what the polls say.
