Projected primary results in Connecticut, Delaware, New York, Pennsylvania and Rhode Island have made it official. Tonight is the night one of the major candidates has clinched his party's nomination for president. That candidate, of course, is Barack Obama.
If you're wondering about Mitt Romney, he still has a ways to go to rack up the necessary delegates. Check back in a month or so and I'll try to take note of when he finally goes over the top.
Thanks, as usual, to the Obama Diary, for collecting all the great pictures.
