If it's a bad argument, it's a bad argument whether it's from a conservative think tank or from someone else. If it's a good argument, it's a good argument whether it's from a conservative think tank or from someone else.

It's up to you to show that is a good or bad argument, rather than committing the logical fallacy of poisoning the well.
