Talk about fuzzy math. President Obama claims higher taxes will account for a mere third — $1 trillion — of his proposed $3 trillion debt reduction over 12 years, not counting less interest expense. Wrong. The actual number is probably around 50 percent of $4 trillion in savings — some $2 trillion — and could be closer to 60 percent. (More details below.) Instead of offering a template for a Grand Compromise, Obama seems to have created a Grand Obfuscation.
