Some of these cases are more complex than the simple "Dems good/Repubs bad" spin some people like to put on it. There's a sub-Secretary-level political nominee position at VA that's been sitting unfilled for going on 5 years. Like most very senior positions at VA, it's traditionally been filled by a veteran. The VSOs (veteran service organizations) that have a lot of pull in Congress have been very insistent that top VA spots go to veterans, and both parties have generally been OK with that. Surveys show that veterans like knowing that veterans are running the show at VA, and both parties and all prior presidents have followed that unwritten rule. Until Obama. When the position became open, he nominated a minority female non-veteran. Minority status was no big deal, because minorities had filled the position before - nothing new there. Being female was new for the position, but plenty of females hold other top spots at VA and elsewhere in government, so really, no one much cared. Her non-veteran status was a big issue, however - the VSOs were quite clear that this was a problem and they would not support a non-veteran in the job. The committee refused to schedule a vote, and the nomination expired. Obama submitted the same nominee two more times, despite even members of his own party telling him a non-veteran VA appointee would not fly! We can debate whether having this "veterans only" unwritten rule for senior VA positions is fair and just, but it didn't just start when the GOP took over Congress - it goes back at least 50+ years. Regardless, Obama decided to ignore it, and we got another blocked nomination as a result.
