I have recently binge-read (I must admit some of the reading was skimming) all of Bob Woodward's books about the presidents between 1992 and 2016. And reading them all at once more or less in order makes one thing really jump out. In the Bill Clinton and Obama books, the congressional Republicans make regular appearances in the narrative. In the George W. Bush books, Democrats in Congress – or anywhere else for that matter – don't exist.
To make sure I wasn't imagining things, I checked the indexes. In State of Denial (late W years) Tom Daschale, Nancy Pelosi, and Harry Reid are mentioned once each. Once. And not in any way that is significant. Reid is quoted as being "disappointed" about some committee appointed to look into money spent in Iraq. Daschale was called to schedule some kind of hearing. Pelosi I couldn't find at all, although the index lists her on a page she does not appear.
The Clinton books, which incidentally I think are the best reads in the sense of being enjoyable, focus predominantly on characters around the White House, obviously. But people like Bob Dole and Newt Gingrich are in it a lot. They are physically present every chapter or so, and when they aren't the White House staff are talking about them. The names of minor Republicans in Congress come up too, as potential targets to be wooed.
It's not just a majority/minority thing; Obama and Clinton had a congressional majority for only two years compared to six* (The Senate was a coin flip for two years, so I guess four years depending on how you look at it) for Bush. That certainly matters. But I think there's more to it than that. Even after losing Congress in 2006, the Bush administration inner circle continued to act as though the Democrats did not exist. What they wanted was not a topic of conversation, even idly.
It could be tempting to write this off as an artifact of Woodward; that for some reason, Woodward was biased and portrayed the situations differently. I find it hard to come up with a convincing logic to support that. As far as Access Journalism goes, Woodward is a pretty reliable Scribe. And I'm unaware of allegations that he has some kind of big bias that leads him to want to write the Democrats out of the Bush story. It seems to reflect the reality around him, that in the Bush White House they didn't particularly give a shit about the opposition party. I think that matches reality to those of us who remember the W years and "unitary executive theory."
Clinton was somewhat successful at getting GOP buy-in, albeit at the cost of constantly giving them (and moderates in his own party) concessions. Obama, though, got nothing. Unfortunately it took him too long to discover that no amount of bringing them to the table or giving them sweeteners was going to get him anything in return.
Anyway, this is hardly an observation I quantified beyond checking the indexes to make sure I'm not crazy. Nonetheless I think it says something that comports with the current election – that Democrats are wired to try to woo moderate Republicans while Republicans make no effort whatsoever.
