Not-so-bold prediction time: The MSM will fawn uncontrollably over this “talkathon” publicity stunt.

WASHINGTON — While Senate Democrats try to turn the nation’s attention to climate change with an all-night talkathon on the Senate floor Monday night, the White House will support them on social media.

A White House official said tweets from senior administration officials and the White House account will be posted Monday to support the Senate Democratic effort, which starts Monday evening and goes through 9:00 a.m. Washington time Tuesday.

Climate activists are also taking to social media to boost exposure for the talkathon. 350.org, the group best known for its anti-Keystone efforts — including amass arrest at the White House fence last week — plans to tweet support under the hashtag #Up4Climate.

At Monday’s daily press briefing, White House Press Secretary Jay Carney praised the talkathon, which is expected to include dozens of Democratic Senators.

“We commend those who are participating, because it’s a very important subject that the president, as you know, is concerned about and has a climate action plan dedicated to addressing,” Carney said.
