Democratic candidate Chris Pappas won the US Senate election from New Hampshire, defeating Republican John Sununo, Reuters reports. The result of the vote allows Democrats to maintain a key mandate in the fight for control of the upper house of Congress, where Republicans previously held a majority of 53 seats to 47. One of the main issues in the campaign in the country was the high energy prices: Pappas blamed the interruptions in the supply of oil and the increase in fuel prices on the Republican policy towards Iran.
