Political Wire has a really interesting post up on how many people are still unfamiliar/undecided with Kerry.

This simple fact has set the strategies for the campaign. To attract on-the-fence voters, Kerry is expanding the use of biographical ads to introduce himself, while President Bush is running negative ads to try to define his opponent first.

In many ways, the presidential race mirrors the 1980 campaign when incumbent Jimmy Carter faced declining approval rates yet the public was unsure of Ronald Reagan, a candidate viewed by many on the ideological fringes of his own party. Reagan’s challenge then — to make himself more appealing to the average voter — is the same as Kerry’s today.
