Arizona, Florida, and Illinois add to the delegate totals as a result of primaries on March 17th. Although initially scheduled for the same day, Ohio's governor and health department delayed that state's election due to the coronavirus pandemic. Even without Ohio, there was a nice haul of 441 delegates for the evening.

Going into the evening, Biden needed at least 223 of those delegates (50.52%), to be on a winning pace. By contrast, Sanders needed 255 delegates (57.78%).

We had discussed after the March 10th states how this was an almost unreachable bar for Sanders. That winning at that level would require a seismic change in the state of the race.

No such massive realignment happened. Although exact delegate totals will continue to shift as counts become final, as of election night, the March 17th results look like:

• Biden 294 (66.7%)
• Sanders 147 (33.3%)

Biden significantly exceeded the marks he needed. Sanders came nowhere near where he would have had to have been.

Everybody else other than Biden and Sanders has now been mathematically eliminated.

Looking at the "% of Remaining Delegates Needed" chart, you can see that Biden's curve heads downward, while Sanders's is clearly on a dramatic upswing.

At this point, Sanders would need 64.19% of the remaining delegates to catch up and win.  Absent scenarios where Biden drops out for health reasons, or something just as catastrophic, there is no reasonable scenario where Sanders wins the remaining races by an average 64% to 36% margin.

We'll keep tracking things, just in case something extraordinary does happen. Because after all, given how 2020 is going, you never know.

But really, the Democratic race is over now. It was a stretch not to say that a week ago. But now, it is undeniably over.

Biden will be the Democratic nominee.

Oh. And look at this…

Although Weld did earn a single solitary delegate along the way (who may or may not make it to the convention floor), Trump clinched the Republican nomination with the March 17th results.

So we're looking at Biden vs. Trump for the general election.

As of the morning of March 18th, that race looks like this:

117.3 days until the Democratic National Convention.

159.3 days until the Republican National Convention.

230.5 days until polls start to close on Election Night 2020.

The real race is just beginning. Get ready.
