You conveniently ignore the "political impact against one candidate" bit.
So your statement only makes sense if you assume that all journalists are trying to influence politics to the benefit of their preferred candidate in their reporting.
My point is, unless he also had info on Trump/Republicans, he couldn’t have impacted their campaign. So impact of just one candidate/party was inevitable. Then, optimise for max impact.
