How much power will Congress let Obama seize?

Would Congress stop President Obama if he unilaterally declared he was raising the federal income tax rates for families that earn between $50,000 and $99,000 per year?

This week, Obama swept aside the plain and unambiguous language in the Patient Protection and Affordable Care Act that he personally signed and fought all the way to the Supreme Court to maintain so he could unilaterally suspend the law‘s requirement that the government extract penalty “payments” from businesses that do not comply with a mandate to provide their workers with health insurance.
