A continuing weak economy and last month’s bipartisan tax cut legislation will drive the government’s deficit to a record $1.5 trillion this year, a new government estimate predicts.

The eye-popping numbers mean the government will continue to borrow 40 cents for every dollar it spends.

The new Congressional Budget Office estimates will add fuel to a raging debate over cutting spending and looming legislation that’s required to allow the government to borrow more money as the national debt nears the $14.3 trillion cap set by law. Republicans controlling the House say there’s no way they’ll raise the limit without significant cuts in spending, starting with a government funding bill that will advance next month.

The CBO analysis predicts the economy will grow by 3.1 percent this year, but that joblessness will remain above 9 percent this year. Dauntingly for President Obama, the nonpartisan agency estimates a nationwide unemployment rate of 8.2 percent on Election Day in 2012.
