Barack Obama won the White House by campaigning against an unpopular incumbent in a time of economic anxiety and lingering foreign policy concerns. He offered voters an upbeat message, praised the nation as a land of opportunity, promised tax cuts to just about everyone, and overcame doubts about his experience with a strong performance in the presidential debates.

Does this sound familiar? It should. Mr. Obama followed the approach that worked for Ronald Reagan. His victory confirmed that voters still embrace the guiding beliefs of the Reagan era.

During Reagan's campaign, the nation suffered from high unemployment and high inflation. This time around, data from the Rasmussen Reports Daily Presidential Tracking Poll showed that Mr. Obama took command of the race during the 10 days following the collapse of Lehman Brothers -- when the Wall Street meltdown hit Main Street. Before that event John McCain was leading nationally by three percentage points. Ten days later Mr. Obama was up by five and never relinquished his lead.

Mr. Obama's tax-cutting message played a key role in this period of economic anxiety. Tax cuts are well-received at such times: 55% of voters believe they are good for the economy. Only 19% disagree and see them as bad policy.

Down the campaign homestretch, Mr. Obama's tax-cutting promise became his clearest policy position. Eventually he stole the tax issue from the Republicans. Heading into the election, 31% of voters thought that a President Obama would cut their taxes. Only 11% expected a tax cut from a McCain administration.

The last Democratic candidate to win the tax issue was also the last Democratic president -- Bill Clinton. In fact, the candidate who most credibly promises the lowest level of taxes has won every presidential election in at least the last 40 years....
