Final answer:
The true statement is that MADD redirected its advocacy from the states to the federal government to successfully raise the national drinking age.
Step-by-step explanation:
The statement about venue shopping that is true is that Mothers Against Dru.nk Driving (MADD) directed its efforts from state governments to the federal government. Venue shopping refers to the strategic actions by interest groups to choose the level and branch of government where they believe their policy objectives have the best chance of success. When MADD found little success in state legislatures with their goal to raise the drinking age, they redirected their advocacy to the federal level. This resulted in the National Minimum Drinking Age Act of 1984 which mandated states to raise the legal drinking age to twenty-one.
In contrast, anti-abortion advocates started at the federal level after Roe v. Wade, but later turned to state governments where they were more successful in advancing restrictions on abortion rights.
