“Primary season is officially here. And the first elections of the midterms expose generational and ideological divides for both parties,” Politico reports.

“The biggest contests on Tuesday night — when elections are being held in Texas, North Carolina and Arkansas — are the Lone Star State’s Senate primaries. Democrats James Talarico and Jasmine Crockett and Republicans John Cornyn, Ken Paxton and Wesley Hunt have spent millions on their respective bids, and across the board it’s still anyone’s guess who will emerge victorious — or if the races will stretch on for an additional three months in high-stakes runoffs.”

“But further down the ballot, there is everything from battles over support for Israel in the Democratic Party to fights over loyalty to President Donald Trump for Republicans. These early races will signal which issues resonate with voters ahead of future primaries — and on to November.”
