Both John McCain and Barack Obama have proposed tax plans that would substantially increase the national debt over the next ten years, according to an updated analysis by the non-partisan Tax Policy Center. Compared to current law, TPC estimates the Obama plan would cut taxes by $2.8 trillion from 2009-2018. McCain would reduce taxes by nearly $4.2 trillion. Under current law, the 2001 and 2003 tax cuts would expire in 2010 and the Alternative Minimum Tax would remain in full force.
