In fairness to the union, journalists would give to Clinton/Sanders regardless.
Via Daily Caller:
Journalists from some of the most renowned publications have indirectly contributed greatly to Democratic candidates, in a potential conflict of interest, due to being unionized, according to reports Tuesday.
The Communications Workers of America (CWA) has contributed to a list of Democrats over the years. It is also the biggest union thus far to endorse Democratic presidential hopeful Sen. Bernie Sanders at 700,000 members. Its political contributions to Sanders might pose a conflict of interest since it represents many print and broadcast journalists.
