If your brothers are like my Dem friends, they are probably in denial. My Dem friends simply swallow everything their lib masters tell them. During the Clinton admin, the Clintonistas told them that Hussein was as threat and had wmds. And my friends believed them. During the Bush admin the same people told my friends that Hussein was not a threat and had no wmds. And my friends believed them. I have remarked on the release of these documents and the damning truth revealed in them, and my Dem friends choose to deny their validity and stick their heads in the sand.
Hopefully your brothers will eventually realize that almost all lib commentators, gov and ex-gov sources and insiders are agenda-driven and/or outright liars. Someday I hope to convince my Dem friends and family members of that obvious fact.
