Markey predicted more Democrats would sign on as the plan gets better known and said some Republicans may back it. It's the old red-baiting line of attack. The nonbinding resolution sets a goal to meet "100 percent of the power demand in the United States through clean, renewable and zero-emission energy sources, " including nuclear power.
Democratic moderates have been less than enthusiastic about the proposal.
Trump is already testing out this approach.
"I really don't like their policies of taking away your vehicle, taking away your airplane flights, of 'let's hop a train to California, ' or 'you're not allowed to own cows anymore!'" he told the crowd.
"I've noted with great interest the 'Green New Deal.' We're going to be voting on that in the Senate; giving everybody an opportunity to go on record and see how they feel about the 'Green New Deal, '" said McConnell.
Sen. Ed Markey, D-Mass, a co-sponsor of the plan, also decried McConnell's move. He wants to silence your voice so Republicans don't have to explain why they are climate change deniers.
The Green New Deal calls to "totally overhaul transportation by massively expanding electric vehicle manufacturing, build charging stations everywhere, build out high-speed rail at a scale where air travel stops becoming necessary", according to Ocasio-Cortez's website.
Democrats say Republicans have failed to address the issue as the majority. Politico says McConnell's campaign team has begun compiling opposition research on McGrath, and Republicans involved in a pro-McConnell super PAC are meeting this week to begin plotting strategy for a possible campaign against her. But the majority leader, and the rest of the GOP for that matter, might be too hasty in thinking it's an Achilles heel for Democrats.
"I think it is very important for the Democrats to press forward with their Green New Deal", he tweeted.
The resolution has amassed significant but by no means widespread support on Capitol Hill - there are 67 co-sponsors in the House and 11 in the Senate, including several current or potential presidential contenders: Bernie Sanders, Kirsten Gillibrand, Elizabeth Warren, Cory Booker and Amy Klobuchar.
To be sure, not all Senate Dems are as enthusiastic. "This, perhaps counterintuitively, makes an up-or-down vote extraordinarily convenient for activists supporting the Green New Deal-from groups like the Sunrise Movement, Indivisible, and the Sierra Club-who will be able to put pressure on those who reject the resolution in the months ahead".
Whatever happens next, it's becoming increasingly clear that the Green New Deal is turning into something the two parties think they can use to their advantage.
