President Barack Obama (D) has won a majority of available delegates for the Democratic presidential nomination and is now the presumptive Democratic nominee. There is no serious national opposition to the president for the Democratic Party nomination, however he has been standing for election in state primaries against some limited opposition including Randall Terry and John Wolfe Jr.

With wins in today’s District of Columbia and Maryland Democratic primaries, Obama is now all-but certain to receive his party’s nomination—an outcome that was essentially assured all along. He will be formally nominated at the Democratic National Convention in September.

Meanwhile, the Republican primary battle continues. Former-Governor Mitt Romney (R-MA) holds a wide lead over his opposition, but is still only about half-way to gaining a majority of available Republican delegates. The Republican National Convention will be held in late-August.
