Obama is a union leader threatening a strike. His membership parrots the party line.
That is the essence of the long litany of horrors that Obama's mouthpieces state will happen if the sequester occurs - closing 100 airport towers, 90 minute delays due to lack of air traffic controllers, loss of border security, food shortages due to lack of USDA inspectors, etc. These are all choices, not absolutes. If we can't reduce the budget by 2.3% of the budget, leaving actual budgets higher than last year, then there is no hope of ever reducing anything the Left wants.
