Are Minneapolis Star Tribune endorsements of any use?

Speaking of the Strib (see below), Matt Stoller has already noted the oddity of the Strib simultaneously endorsing Obama for president while backing Franken's Republican opponent, Norm Coleman, for the U.S. Senate.

But as mnblue now points out, the Strib's other Congressional endorsements are so poorly argued and executed (Democrat Steve Sarvi wasn't even interviewed by the Strib ed board before it endorsed his GOP opponent), you have to wonder if they'll carry much weight with voters.
