18. Adding Up the Cost of Obama’s Agenda When campaigning, Barack Obama has made a long list of promises for new federal programs costing tens of billions of dollars. Obama has said he would strengthen the nation’s bridges and dams ($6 billion a year), extend health insurance to more people (part of a $65-billion-a-year health plan), develop cleaner energy sources ($15 billion a year), curb home foreclosures ($10 billion in one-time spending) and add $18 billion a year to education spending. In total a $50-billion plan to stimulate the economy through increased government spending. A different blueprint offered by McCain proposes relatively little new spending and tax cuts as a more effective means of solving problems. Source: Los Angeles Times, July 8, 2008
