Presidential candidates use their formal announcements to introduce themselves to American voters. Many do so in their hometowns: Bill Clinton in Little Rock, Bob Dole in Russell, Kan., and, in a few weeks, Rep. Michele Bachmann in Waterloo, Iowa.
Others, though, seek to create an image they want to place before the voters. Former Massachusetts Gov. Mitt Romney recently declared his candidacy on a New Hampshire farm with a sharp attack on President Barack Obama's stewardship of the American economy.
