Trump's endorsement power tested in South Carolina battle to succeed Lindsey Graham
MADISON, Wis. - Polls closed Tuesday evening in South Carolina and Vermont, kicking off a consequential night of primaries headlined by the battle to succeed the late Sen. Lindsey Graham and another test of President Donald Trump's endorsement power. Far-left frontrunners Francesca Hong and Peggy Flanagan worry moderate Democrats about general election prospects. But some of the night's biggest political fireworks are still to come in the Midwest, where Wisconsin and Minnesota are the key battlegrounds in the high-stakes fight between the left-wing and the center-left establishment for the future of the Democratic Party. After far-left candidate Abdul El-Sayed narrowly edged out more moderate Rep. Haley Stevens a week ago in battleground Michigan's Democratic Senate primary, the spotlight now shifts to statewide nomination showdowns Tuesday in Wisconsin and Minnesota.
