Points from this article were taken from the Heritage Foundation. Barack claims his budget will cut the deficit in half by the end of his term.

I assume he means 4 years because he can't assume that he will be President for 8 years.

Brian Riedl, Heritage Analyst, points out that "Obama has already helped Quadruple the deficit with his stimulus package, pleding to halve it by 2013 is hardly ambitious." What’s driving Obama’s unprecedented massive deficits? Spending. Riedl details:

• President Bush expanded the federal budget by a historic $700 billion through 2008. President Obama would add another $1 trillion.
• President Bush began a string of expensive finan­cial bailouts. President Obama is accelerating that course.
• President Bush created a Medicare drug entitle­ment that will cost an estimated $800 billion in its first decade. President Obama has proposed a $634 billion down payment on a new govern­ment health care fund.
• President Bush increased federal education spending 58 percent faster than inflation. Presi­dent Obama would double it.
• President Bush became the first President to spend 3 percent of GDP on federal antipoverty programs. President Obama has already in­creased this spending by 20 percent.
• President Bush tilted the income tax burden more toward upper-income taxpayers. President Obama would continue that trend.
• President Bush presided over a $2.5 trillion increase in the public debt through 2008. Setting aside 2009 (for which Presidents Bush and Obama share responsibility for an additional $2.6 trillion in public debt), President Obama’s budget would add $4.9 trillion in public debt from the beginning of 2010 through 2016.
