DES MOINES, Iowa (AP) - Democratic presidential hopeful John
Edwards is getting some star power by appearing at a free John
Mellencamp concert Wednesday. Republican Mike Huckabee will be taping the "Tonight Show."
It's the last full day of campaigning before Thursday's caucus.
Tuesday, volunteers spent most of their time making telephone
calls and going door to door to get out the vote.
One poll says Senator Hillary Rodham Clinton and Mitt Romney are
leading. Another says Senator Barack Obama and Mike Huckabee are
ahead. Many voters haven't locked in their support yet.
At least 130,000 Democrats and 80,000 Republicans are expected
to participate in nearly 1,800 neighborhood meetings across Iowa.
