After many hard-fought months, the presidential primary season effectively drew to a close as Hillary Clinton notched major wins in New Jersey and California — all but guaranteeing her becoming the first female major party presidential nominee.

With no opponents remaining, Donald Trump was already the presumptive Republican nominee, and Clinton had been awarded that mantle for the Democrats Monday night based on NBC's count of both pledged and so-called "super" delegates. But voters in California, New Jersey, New Mexico, North Dakota, South Dakota and Montana took to the polls on Tuesday to cast their votes for the former secretary of state or her last remaining opponent, Sen. Bernie Sanders of Vermont.
