I chose other, and would fill it with Franklin Roosevelt (at the risk of stirring up rants and raves.) I just think he looms pretty large in the development of the modern USA.
Yes and no.
Yes, if we mean 'large in the development of the USA'. Of course, he was elected to 4 terms! And this was during the depression and WWII, so it was a critical time as well. Not sure if his pro Soviet policies were so good, though. Stalin was probably even worse than Hitler so it was a big mistake to help him stay in power and then to give half of Europe over to him after the war.
His economic policies for dealing with the depression were so effective that it only lasted a decade! He started social security which worked out great for the first generations under it. They got back so much more than they paid. Of course, now that is being reversed and current generations won't come close to getting back the money collected from their paychecks.
(I'd still pick him over MLK, though. Thomas Sowell said, "One of the sad signs of our times is that we have demonized those who produce, subsidized those who refuse to produce, and canonized those who complain”. MLK falls in the last category, just a complainer. Like Albino Smurf points out, it's better to be a worker.)
