text: Of course there is always a downside to everything. This flaw is that, when you're voting, you're not voting for who you believe you are voting for. As said in source 2, when you vote for your president, the vote doesn't go to the president, but for the slate of electors, who in turn elect the president. This may not sound so bad, but with something such as this, there could easily be some corruption in that and could change the outcome of the election. But even with this said, it's an unlikeble chance. when you vote, the elector you voted for is most likely going to be an elector which will vote for your president. So no worries.
