I just did that search as an off-the-cuff experiment without taking the time to do the search you suggested. It's interesting at how Tom did the search using the complete phrase "Republicans seized control" verses "Democrats seized control." The differences there are much more noticeable.

If I had the time (which I don't), it would be interesting to go through a couple hundred sample articles from both of those searches and see how the articles used the phrase "seized control" in regard to Republicans verses Democrats.

My whole point is that, to read some sources, "Democrats win elections" but "Republicans seize control."

Words mean things.
