Since Dale Earnhardt Jr. won the Most Popular Driver award 15 straight times, there’s no dispute which driver was the most liked by fans in the last decade and a half.

But who were the other popular drivers during that time? Well, we actually know the answer to that question because the National Motorsports Press Association (which administers the award) has released a top 10 of the voting each year since Earnhardt first won it in 2003.

Only seven of the current 10 most popular drivers will return next season — Ryan Blaney, Kyle Busch, Chase Elliott, Jimmie Johnson, Kasey Kahne, Kyle Larson and Martin Truex Jr. That’s in alphabetical order, because the NMPA no longer releases the order of the final voting (they used to not only release the order, but also the vote totals).

Who will the other three be? It seems fairly wide open at the moment.

That’s because only two active drivers — Kevin Harvick and Brad Keselowski — have ever made the top 10 in the past and failed to make it this year.

All other active drivers — including the likes of Denny Hamlin, Joey Logano and Clint Bowyer — have never appeared on the top 10 list.

At the bottom of this post, I’ve compiled a spreadsheet of all the data dating back to 2003. But first, a few observations:

— What happened to Harvick? This is the biggest mystery from the voting. Harvick was the third-most popular driver in 2003 and 2004, then dropped to the bottom half of the list over the next decade — but was still in the top 10 for every year from 2003-13. But he has now missed the top 10 in three of the last four years (starting with the year he won the championship, oddly enough). Perhaps it’s because he’s been more affected than anyone with old-school fans abandoning the sport (assuming his fan base early on had a large portion of Dale Sr. fans after he took over that ride in 2001). What are some other theories?

— Truex on the rise. Martin Truex Jr. never made the top 10 in voting until the past two seasons — this despite being a full-time driver since 2006.

— New faces emerge. Ryan Blaney and Kyle Larson both made the top 10 in voting for the first time this season. Chase Elliott has made it in each of his first two years.

— Streak continues. Of the remaining active drivers, who has the longest streak of making the list? It’s a tie between Jimmie Johnson and Kasey Kahne, who have both appeared every year since 2004. But while Johnson has typically been in the bottom half of the voting when the order has been revealed, Kahne is usually toward the top (and got as high as second in 2013).

— That 2014 list! Seven of the 10 drivers from 2014 are no longer in the sport full time. Of course, that’s a bit misleading since Josh Wise made the top 10 that year based on the Reddit push. But the other six drivers (Earnhardt, Carl Edwards, Jeff Gordon, Matt Kenseth, Danica Patrick and Tony Stewart) took up a combined 68 spots in the top 10 over 15 years — and that’s going to be hard to replace.

Here’s the spreadsheet I compiled if you want to look at the raw data. “Yes” signifies they appeared in the top 10 that year; in years when the NMPA released the order, the driver’s position in the top 10 is noted.
