I have a bit of a hard time understanding why so many people think this is written by Russians. Obviously the grammar is not correct, but it would seem very strange to think this has any significance, and it seems more plausible that it was done in an attempt to hide the authors identity. (My spontaneous feeling was that it was written by Jar Jar Binks, and not Russians, for whatever that's worth.)

I'm not from the US and have not followed the news from there recently, but from what little I have seen much of the actual contents of the message does seem to reflect the feelings of Trumps "base"? Or would people more familiar with US politics say this is incorrect?
