A good example is the Iraq war debate. What, exactly, is their position? After all, they all believed, when Bill Clinton was president, that Saddam Hussein had a WMD program and threatened to remove him from power. Then, under George W. Bush, when the country supported going to war to do just that, they voted in favor of the war, for dozens of reasons, many having nothing to do with WMD. Now that the war is unpopular, they're against it, … except not really, because they overwhelmingly supported a new commander for the war's continued prosecution and funds to keep it up.
So … when Democrats talk about the war, they're probably being dishonest, unless they come out with their real position: "I have no idea what we should do about Iraq, except that you should blame the guy in the White House for everything bad going on there."
It's the same with this nonsensical pseudo-scandal surrounding U.S. Attorney General Alberto Gonzales. Democrats couldn't care less what he did or didn't do, whether he's doing a good or bad job, who he's hiring and firing, what policies he does or doesn't institute at the Justice Department or anything else about the man. Except that he's vulnerable and close to President Bush. Everything else is just, well, lying.
