Sen. Lindsey Graham (R-SC) is wasting no time launching his reelection campaign, enlisting the likes of Vice President Mike Pence to ward off any potential primary challengers.

According to the Washington Post, Democrats’ 2018 inroads in the state have made Graham’s aggressive pendulum swing to the right risky, as he may shed moderates and independents who have contributed to his winning coalition in the past.

Jaime Harrison, the first black chairman of the state Democratic party, is reportedly considering a bid and would likely be able to count on support from 2020 presidential candidates, since South Carolina has one of the first primaries.
