What's your thoughts on Trump?

My understanding is they created the electoral college because they did not trust the "common man" to vote in an informed way.

It depends on who you ask/where you look. The nation was relatively small but also still influenced by the political structures and beliefs of the British and the men trying to figure out how to select a President had a number of issues to work out without really knowing how it would go, but hoping to avoid the pooling of too much power in one place. From this site:

The Constitutional Convention considered several possible methods of selecting a president.

One idea was to have the Congress choose the president. This idea was rejected, however, because some felt that making such a choice would be too divisive an issue and leave too many hard feelings in the Congress. Others felt that such a procedure would invite unseemly political bargaining, corruption, and perhaps even interference from foreign powers. Still others felt that such an arrangement would upset the balance of power between the legislative and executive branches of the federal government.

A second idea was to have the State legislatures select the president. This idea, too, was rejected out of fears that a president so beholden to the State legislatures might permit them to erode federal authority and thus undermine the whole idea of a federation.

A third idea was to have the president elected by a direct popular vote. Direct election was rejected not because the Framers of the Constitution doubted public intelligence but rather because they feared that without sufficient information about candidates from outside their State, people would naturally vote for a "favorite son" from their own State or region. At worst, no president would emerge with a popular majority sufficient to govern the whole country. At best, the choice of president would always be decided by the largest, most populous States with little regard for the smaller ones.

Finally, a so-called "Committee of Eleven" in the Constitutional Convention proposed an indirect election of the president through a College of Electors.

The function of the College of Electors in choosing the president can be likened to that in the Roman Catholic Church of the College of Cardinals selecting the Pope. The original idea was for the most knowledgeable and informed individuals from each State to select the president based solely on merit and without regard to State of origin or political party.

The structure of the Electoral College can be traced to the Centurial Assembly system of the Roman Republic. Under that system, the adult male citizens of Rome were divided, according to their wealth, into groups of 100 (called Centuries). Each group of 100 was entitled to cast only one vote either in favor or against proposals submitted to them by the Roman Senate. In the Electoral College system, the States serve as the Centurial groups (though they are not, of course, based on wealth), and the number of votes per State is determined by the size of each State's Congressional delegation. Still, the two systems are similar in design and share many of the same advantages and disadvantages.

The similarities between the Electoral College and classical institutions are not accidental. Many of the Founding Fathers were well schooled in ancient history and its lessons.

It seems to me this accidentally caused exactly what they were trying to avoid, which is easily swayed uneducated folks voting for a demagogue.

Sadly, an uninformed public can do some very destructive things, and we've gone from a society that had too few reliable sources of information to one that has too many unreliable sources instead.
