“Democrats fighting to flip four Orange County GOP-held congressional districts appear to have weathered their first challenge: surviving Tuesday’s primary election to advance to November runoffs,” the Orange County Regiater reports.

“The four races have drawn national attention due to their potential to help Democrats shift the balance of power in Congress. But a glut of Democratic candidates in three of the contests threatened to split the party’s vote in a way that allows two GOP candidates to advance, locking out Democrats and thwarting a blue wave of enthusiasm.”

“But early Wednesday it appeared Democrats had dodged their nightmare scenario by finishing among the top two vote-getters in all four districts.”

Los Angeles Times: “However, with a large number of mail ballots still to be counted, it could be days before results are certain.”

Lauren Arthur (D) won a Missouri state senate seat in the Kansas City suburbs by 19 points, in a district which backed both Donald Trump and Mitt Romney by 4 points, the Washington Post reports.

Arthur’s victory is the 42nd red-to-blue flip in state legislative races since the inauguration of President Trump.
