If you paid any attention to President Obama’s recent efforts to assign all blame for the federal government’s spendthrift ways on his predecessor, a new Forbes column from Peter Ferrara of the Heartland Institute should give you enough data to set your mind at ease.

First, Ferrara details the role then-Sen. Barack Obama and fellow congressional Democrats played in ramping up federal spending during the final years of the Bush administration. Next, Ferrara details the 44th president’s role in adding more fuel to the fire once he moved into the White House.

Note as well that President Reagan didn’t just go along with the wild spending binge of the previous Democratic Congress for fiscal year 1981 when he came into office on January 20 of that year. Almost no one remembers now the much vilified at the time 1981 Reagan budget cuts, his first major legislative initiative. Then Democrat Rep. Phil Gramm joined with Ohio Republican Del Latta to push through the Democratic House $31 billion in Reagan proposed budget cuts to the fiscal year 1981 budget, which totaled $681 billion, resulting in a cut of nearly 5% in that budget. Obama could have done the exact same thing when he entered office in January, 2009, even more so with the Congress totally controlled by his own party at the time. …

… In sharp contrast to Reagan, Obama’s first major legislative initiative was the so-called stimulus, which increased future federal spending by nearly a trillion dollars, the most expensive legislation in history up till that point. We know now, as thinking people knew at the time, that this record shattering spending bill only stimulated government spending, deficits and debt. Contrary to official Democrat Keynesian witchcraft, you don’t promote economic recovery, growth and prosperity by borrowing a trillion dollars out of the economy to spend a trillion dollars back into it.

But this was just a warm up for Obama’s Swedish socialism. Obama worked with Pelosi’s Democratic Congress to pass an additional, $410 billion, supplemental spending bill for fiscal year 2009, which was too much even for big spending President Bush, who had specifically rejected it in 2008. Next in 2009 came a $40 billion expansion in the SCHIP entitlement program, as if we didn’t already have way more than too much entitlement spending.

But those were just the preliminaries for the biggest single spending bill in world history, Obamacare, enacted in March, 2010. That legislation is not yet even counted in Obama’s spending record so far because it mostly does not go into effect until 2014. But it is now scored by CBO as increasing federal spending by $1.6 trillion in the first 10 years alone, with trillions more to come in future years.

After just one year of the Obama spending binge, federal spending had already rocketed to 25.2% of GDP, the highest in American history except for World War II. That compares to 20.8% in 2008, and an average of 19.6% during Bush’s two terms.
