Yes there a many conflicting interests even at the top of the capitol class, they compete for money and influence, and are often narcissists looking to one up each other. They will only close ranks when threatened and only in very specific areas like tax dodging. The vast majority of pressure capitol gets in the west is from other capitalists looking to displace them as the left is so weak. In this case if the right-wing talking heads took the pro-vax money anti-vax talking heads would just step in to replace them.
