Voters went to the polls in five states yesterday: New York, Massachusetts, New Hampshire, Rhode Island and Delaware. They were the final primaries before the November elections. Former Massachusetts Sen. Scott Brown became the Republican nominee for Senate, this time from New Hampshire. He’ll face Democratic Sen. Jeanne Shaheen in a race that could have implications for control of the Senate. In Massachusetts, an upset in the 6th Congressional District is the first to oust a sitting Democrat in the state in more than two decades. And in Rhode Island, Gina Raimondo won the Democratic nomination for governor despite controversy over her public pension overhaul. At the end of a primary season that began six months ago in Texas, we look at what the results could mean for Democratic and Republican prospects in November, control of the Senate and Barack Obama’s presidency.
