Republicans just voted a huge tax cut for the wealthiest individuals and corporations that completely blew up the deficit. They also passed a budget that put billions into the defense budget, further magnifying the deficit. Obviously they don't really care about a balanced budget. Passing a balanced budget amendment now gives them an excuse to cut social security, medicare, medicaid, food stamps, healthcare, research and any other social programs that benefit the vast majority of ordinary citizens. If they want to balance the budget they should start by taxing the rich, cutting out oil and gas subsidies, and putting price controls on prescriptions for medicare, medicaid and health insurance. When they do that, I might believe they actually care about the deficit.
