Not a chance. He was already teetering before this hit.
First, keep in mind the Presidential election is really about just 8 or 9 states (PA, FL, OH, MI, WI, MN, IA, NV, AZ), and remember he really has to win all of them (or all but one depending on the one). All the other states are locked in already. Now look at how he's doing in those states today - he's down big in all but two, one of them (OH) he's pretty strong. The polls have error in them you say? Of course they do. So don't take them at face value, compare them on trend. Look where he his now versus November of 2016. He won by a whisker in 2016 and he's collapsed back in support in almost every state in contention for this cycle.
Second, there is a crisis curve when it comes to Presidential support. Typically when a crisis hits, very shortly after, support for the President spikes up, no matter who the President is. Then, after some months of seeing the effects, they settle back. Now look at Trump's approval ratings in the past two weeks. They didn't spike, but didn't go down either - they are really in the same place they were. So best case for him, his numbers are inelastic to events, which takes me up to my first point. Worst case for Trump, he gets the slide down, and will be in an even worse position.
Third and finally, this race will come down (in my view) to one thing - turnout among Democrats and Independents. Why? Because Republicans turn out reliably anyway, cycle after cycle. Democrats and independents don't. This is something the left has always struggled with. They didn't show up in 2016 because it looked like the race between two evils to a lot of people. This time? Look at the 2018 midterms. There is a deep anger among those not very conservative, against Trump. It drove huge turnout in 2018, and boom, blue wave. If the left and center are still angry in November 2020 (and I'd bet they will be), they will show up in much larger numbers. And then not only does Trump lose, he loses big.
Feel free to call me on this in November. This is my guess. I could be wrong, but I feel pretty good about it. Trump's chances in November are less than 20%.
