The state's new political map is being put to the test for the first time as primary elections are held in freshly-redrawn congressional districts across Massachusetts.

The new districts reflect the loss of one of the state's 10 seats in the U.S. House due to population shifts.

Officials predict only about 15 percent turnout statewide, but the numbers are expected to be stronger in some areas including the reconfigured 9th District, where freshman Rep. William Keating is being challenged in the Democratic primary by Bristol District Attorney Sam Sutter.

Interest is also running higher in the 4th District, where three Democrats and three Republicans are vying for the seat being vacated by Rep. Barney Frank. The Democrats include 31-year-old Joseph Kennedy III, the first Kennedy family member of his generation to seek political office.
