Organizers say a Tea Party rally in Duluth Sunday could attract thousands to hear Wisconsin Republican U.S. Sen. Ron Johnson give the keynote address.

The noon rally at Amsoil Arena is sponsored by the Northern Liberty Alliance, along with Tea Party groups from Wisconsin and Michigan.

The rally will include a presidential poll; nationally, Tea Party leaders have supported candidates Rick Santorum, Michele Bachmann and Herman Cain, who have all dropped out. Ron Paul has seen strong support among some in Minnesota.
