Democratic senators declined to participate in a high profile March filibuster supporting a carbon tax. Nearly half the democrats in the US Senate declined to take part in the democratic climate action task force March filibuster supporting a carbon tax. Democrats control the Senate and have more than enough votes to pass a carbon tax. Not only did nearly half the Senate democrats decline to participate but moderate democrats and democrats from political swing states were almost entirely absent from the filibuster vote. This underscored how few politicians in the Congress whether in the House or the Senate are foolish enough to spend their political capital on a mythical global warming crisis and costly futile program to address it. Another crushing defeat for Obama.
