Last night in Arizona, a special election was held to fill a congressional seat that should have been an easy pickup for the GOP. It wasn’t. The party spent over a million dollars in a district that Donald Trump won by 21 points. In the end Republican Debbie Lesko won the race, but the margin will give her party pause.

The win reverses a tide of Democratic pickups in special elections. But the trend continues to shade blue. From Axios:

“Top Republicans have conceded for months that they’re likely lose the House in November’s midterms. But some well-wired operatives now tell Jonathan Swan and me that President Trump may face his real nightmare: losing the Senate, giving Democrats both ends of the Capitol, and one-third of the government.”
