In less than a month, voters will cast a ballot for president of the United States. The Washington Post gets information for some of those stories by travelling with each candidate. If Democratic nominee Hillary Clinton or Republican nominee Donald Trump decides to hold a rally in Kansas or California,

How many stories, posts, tweets do you typically write each day?
Johnson: I usually write at least one article each day, but sometimes it's as many as five. I also share news with readers on Twitter, Facebook and Snapchat.
Phillip: Usually, I might write one story a day. (This might be something that we publish in the newspaper.) But in that same day, I might write a blog post or two as well. We tweet constantly! During rallies, I'll tweet out interesting or new comments from Clinton. I try to tweet pictures and videos of what I see and hear. So at the end of the day, I might have tweeted 40 or 50 times - if not more!

How often do you get to talk to the candidate?
Phillip: Since Clinton got a campaign plane after the Democratic National Convention, we have talked to her at least once, sometimes twice a week. She may come to the back of the plane where all the journalists sit and say hello. Or, she might have a news conference, where she stands at a lectern and takes questions. Other than that, we aren't usually allowed to get close enough to her to talk with her.
Johnson: Not very often. Trump used to regularly talk with the reporters who cover him, but he has been doing fewer and fewer interviews. The last time he had a formal news conference was July 27.
What has been the biggest challenge in covering the candidate?
Johnson: Trying to write an article while running to a bus to catch the next flight to the next rally.
Phillip: The biggest challenge in covering Clinton is lack of access. One of the most important things we can do as journalists is ask candidates questions on behalf of voters. Until recently, we haven't been able to do that very often. That is changing a bit, and I think it has been a big improvement.

What's the funniest thing you have seen or experienced on the campaign trail?
Phillip: At a stop in Pennsylvania recently, one of the campaign volunteers who drove a van in Hillary Clinton's motorcade had a familiar name: Bill Clinton. The man was born almost at the same time as Hillary Clinton's husband, and his real name is William Joseph Clinton. Pretty similar to former President William Jefferson Clinton. Hillary Clinton took a photo with the van driver, and when he told her his name, she said, "You're kidding me!"
Johnson: In the (northern) spring, we followed Trump to Scotland, where he attended a ribbon-cutting for a new luxury hotel - and we quickly had to learn how to drive on the left side of the road.
What's something people probably don't know about your candidate that would interest them?
Johnson: Trump flies around the country in a customised Boeing 757 jet that has several bedrooms, leather seats and 24-karat-gold-plated seat belts.
Phillip: Hillary Clinton is a hot-sauce fanatic. She likes to carry around hot sauce on the campaign trail and says that eating spicy food is really good for her health!
