Glenn Beck, Frederick Douglass Defend Bachmann

Posted on Youtube in January, Glenn Beck does his Balloon Head rant against Chris Matthews, explaining that Michele Bachmann is correct when she says the Founders worked tirelessly to elimiinate slavery. Here's what Frederick Douglass said about slavery and the Constitution:

In that instrument I hold there is neither warrant, license, nor sanction of the hateful thing; but, interpreted as it ought to be interpreted, the Constitution is a GLORIOUS LIBERTY DOCUMENT. Read its preamble, consider its purposes. Is slavery among them? Is it at the gateway? or is it in the temple? It is neither.

Now, take the constitution according to its plain reading, and I defy the presentation of a single pro-slavery clause in it. On the other hand it will be found to contain principles and purposes, entirely hostile to the existence of slavery.
