His alliance with Trump and his fierce defense last September of Kavanaugh as the judge faced sexual misconduct allegations are likely to be key points of attack for a potential Democratic challenger.

The Post and Courier reported that Jaime Harrison, associate chairman of the Democratic National Committee, is considering a bid to challenge the three-term senator.

Trump has said Pence will be his running mate again in 2020.
