Conventional wisdom

A comparison of key words spoken by the Republican and Democratic presidential candidates during their convention speeches.

George W. Bush stressed tax cuts and leadership (repeating three times: ''This administration had its chance. They have not led. We will.''). Vice President Al Gore cast himself as a candidate who would ensure ''that our prosperity enriches not just the few, but all working families.''

In the first presidential campaign after the attacks of Sept. 11, 2001, war and terrorism were key themes during both conventions. George W. Bush stressed freedom, both at home and abroad, while John F. Kerry famously declared, ''I'm reporting for duty.''

After eight years of the Bush administration, Sen. John McCain repeatedly said he would fight for the country and urged Americans to ''fight with me.'' Barack Obama talked a lot about keeping promises and bringing change to Washington.

With the economy as the central issue of the campaign, both Mitt Romney and President Obama focused much of their speeches on jobs and taxes.
