A Question for People in the Traditional Media

People in the traditional media tend to emphasize or even sensationalize stories of  extramarital or unconventional sexual activity by conservatives and ignore those about  leftists.  They often try to justify it  by claiming that it is not a result of political bias because what they are focusing on is hypocrisy and not deviations from traditional norms as such.  Since conservatives  are more likely than leftists to claim to adhere traditional Christian doctrine on sex, they are more likely to be fair game for identification and calumny as hypocrites.  

That raises a question. If hypocrisy is what is decisive, why have the same people in the media not reacted similarly to the hypocrisy of leftists including  Sanders, Warren, and many others who preach and moralize endlessly in favor of  equality of wealth and income while amassing fortunes?  One may await an explanation showing how there is no problem of honesty or consistency here.
