MADISON, Wis. (AP) _ Indiana Gov. Mike Pence will deliver the keynote address at the Wisconsin Republican Party state convention next month. The party announced Thursday that the first-term governor will give the speech at the annual gathering on May 3. Other speakers include Wisconsin Gov. Scott Walker, U.S. Sen. Ron Johnson and U.S. Rep. Paul Ryan. Pence says in a statement that he was excited to join with fellow Republicans to unite behind Walker, who is running for re-election this year. Pence says that unlike ``the failed leadership in Washington, states are leading the way forward with real change and a renewed focus on the taxpayer, not on bigger government.'' Walker is being challenged by Democrat Mary Burke, a former Trek Bicycle Corp. executive and state commerce secretary.
