Democrats have a one-seat majority in the Wisconsin Senate after three Republicans lost seats in historic recall elections, but 16 seats are up for grabs in November, and with them the balance of power. In recent weeks, many have focused on the race between Congresswoman Tammy Baldwin and former governor Tommy Thompson, which may determine who holds the majority in the U.S. Senate, but the state Senate races are significant because many Wisconsinites are concerned about having a firewall against embattled Governor Scott Walker's 2013 legislative agenda.
