Against: O'Keefe is not a perfect journalist, as agenda-driven as anyone anywhere
For: These people were on the payroll, fired right after it happened, and Bob Creamer met with Obama 300 times. https://www.reddit.com/r/the_donald has done a great job "following the money" even if they are massively biased.
My vote is still up for grabs (tonight's debate might settle it), but a YUGE part of me does want to see an impartial investigation. The kind we won't get with Comey/Clinton/Lynch.
Side note - very good PR of them to drop the video right after Obama criticized Trump for his rigging claims.
