Sen. Amy Klobuchar (D-MN) says she is “thinking about a 2020 presidential run” and touted her ability to “work really hard to go not just where it’s comfortable.”

During an appearance on ABC News’ This Week, Klobuchar told host George Stephanopoulos: “Well, people are talking to me about this, I think, in part because I’ve worked really hard to go not just where it’s comfortable but where it’s uncomfortable.”

“I did well in a number of those places that Donald Trump won,” Klobuchar added.

Separately, Sen. Sherrod Brown (D-OH) also told Stephanopoulos that he was seriously considering a 2020 presidential run as well. Both Brown and Klobuchar won reelection with a comfortable margin in the 2018 midterm elections.

Term-limited Ohio Gov. John Kasich (R) said he was also “seriously considering a 2020 bid because the country “needs new leadership.” He told ABC News: “These are earnest conversations that go on virtually every day with some of my friends, with my family. We need different leadership. There isn’t any question about it.”

Sens. Amy Klobuchar and Sherrod Brown aren’t the only Democrats mulling a 2020 presidential run. The list also includes Terry McAuliffe, Sen. Kamala Harris, former VP Joe Biden, Michael Bloomberg and Deval Patrick.
