(CNN) —  

Where the presidential candidates spend most of their time says a lot.

We looked at data showing the number of campaign visits from each of the four early-voting states: Iowa, New Hampshire, Nevada and South Carolina. Who’s spent the most time campaigning in each state might surprise you.

In Iowa (thanks to data from the Des Moines Register), it’s John Delaney, with more than 230 events – though it does help that he’s been running for president since summer of 2017. Behind him: Amy Klobuchar has held 114 events in Iowa and Julián Castro has held 108.

That doesn’t directly translate to success in the polls: Delaney and Castro registered a whopping 0% in the latest CNN/Iowa poll. Klobuchar has a more promising 6%, perhaps helped by the Minnesota senator’s neighboring-state name recognition, but nowhere near current Iowa front-runner Pete Buttigieg’s 25%. 

It’s a similar story in the other early-voting states.

New Hampshire’s most frequent flier? Among Democrats, it’s Tulsi Gabbard, with 45 events, followed closely by Klobuchar’s 44 events, then Marianne Williamson with 43, according to data from New Hampshire Public Radio. Gabbard and Williamson both have 0% support in the latest CBS/YouGov poll, while Klobuchar clocks in at 3%. Republican Bill Weld has actually held the most events there, with 66 total.

Candidates have visited Nevada the least of the early states – by far. Kamala Harris has made the most stops there in the 2020 cycle, with 14 visits, according to the Nevada Independent’s data. Harris is sitting at 4% support, according to the latest Fox News poll.

And in South Carolina, Harris and Cory Booker, who have worked to boost their profiles among black voters, have made the most stops. As of now, that face time isn’t showing up in polling. A recent Quinnipiac poll showed Harris at 3% and Booker at 2%. 

On the GOP side, President Donald Trump has been on the trail in recent months, too. He held a homecoming rally Tuesday night to mark his recent official move to south Florida.

The Point: Candidates’ time on the trail, of course, is a long-term investment. But with just under 70 days left until the Iowa caucuses, there’s not a lot of time left to see that big payoff.
