Joseph Smith could have been talking about himself.

If he was talking about himself, it was a failed prophecy (one of many of his)

[asparagus]

The church never confirmed this "prophecy" and was never published in Joseph Smith's writings. It appears to be an urban legend.

The Stephen Douglas story is a good one. This link provides a great discussion on Joseph's encounter with Stephen Douglas in 1843, 17 years before Douglas was nominated for President by the Democrat Party. Douglas smeared the Saints in 1857 and fulfilled the prophecy. In 1860, he lost the election, carrying only the State of Missouri, and died a year later.<> http://www.jefflindsay.com/LDSFAQ/FQ_prophecies.shtml#douglas
