All three of NASCAR's national touring series have two races left on the 2024 schedule.

Obviously, there will be one remaining after this weekend at Martinsville, where four drivers (and teams) from each circuit will go to Phoenix next week with a chance to win a championship.

In each series, a few drivers are outside the top four and so far down in points, a win at Martinsville is their only chance to take championship hopes to the desert next weekend.

Smell that? It's drama.
