Democrat Troy Jackson unseated Republican Senator Susan Collins in United States Senate voting, delivering a pickup for Democrats in a closely watched midterm race. First elected in 1996, Collins fell to economic headwinds after decades as a moderate in a state that has not backed her party for president since 1988. The upset alters the balance of power as Democrats fight to net four seats to take control of the chamber.
