To block Trump, a majority of delegates at the convention would simply have to vote to change their rules, to free themselves up to vote for whichever candidate they want. And then they'd just … nominate someone who's not Donald Trump.

This may seem shockingly undemocratic, but it's completely possible given how the convention works. The delegates get to set their own rules, and no higher body can overrule them. So they're perfectly free to change those rules at the last minute — even if those changes are obviously meant to alter the outcome of the race.

At their darkest moment in Mordor--on the barren plains of Gorgoroth--with their journey seemingly going on forever like an "ever-darkening dream," Sam and Frodo escape in hallucinations, imagining they're back in sunny Hobbiton. In this waste land, with Mount Doom billowing black smoke into the sky, even the stars are blotted out at night. Sam never lets go of the phial of Galadriel, however. He wears it around his neck--a glowing symbol of goodness and hope, the antithesis to the evil Ring of Doom on its golden necklace, weighing down Frodo's head like a millstone.
