Why it matters: Giddy House Republicans hope they can ride this message into 2020 — just as Dems seized their winning 2018 midterm message as soon as House Rs voted in 2017 to weaken protections for pre-existing conditions.

The Green New Deal introduced by Rep. Alexandria Ocasio-Cortez has become a powerful symbol of the issue that President Trump teed up in his State of the Union address when he said: “[W]e renew our resolve that America will never be a socialist country.”

The liberal proposals of Democrats’ 2020 candidates, most notably Sen. Elizabeth Warren’s “wealth tax,” give Republicans more ammunition.

Senate Majority Leader Mitch McConnell tells Fred Barnes in a Wall Street Journal opinion piece about Ocasio-Cortez: “I can pretty safely say this is the first time in my political career that I thought the essence of America was being debated.”
