An advocacy group is providing support to candidates who want to expand support for child and elder care in the midterm elections. The Campaign for a Family Friendly Economy plans to spend $50 million to back Democrats in congressional races. The announcement comes as the cost of child care continues to rise and as waiting lists for federal child care subsidies continue to grow. American families face a slew of costs, including surging gasoline prices driven by a war in the Middle East that is unpopular with many voters. Republicans have begun to back child care as an issue crucial to growing the workforce, but their proposals tend to be less dramatic than those offered by Democrats.
