It just exhausts me that younger office-holders (especially those of color) have such difficulty moving up in my party, even when they may be a better choice. Republicans seem to be better at moving younger people up the ranks (maybe because they have less of a problem with challenging one another) and that should give Democrats pause about the future. We're still dominated by old white folks in the Democratic party despite that not being what most of our base is and even though those old white folks maybe aren't the best choices for us anymore. It's really frustrating sometimes.

GOP has hard time governing because of the turnover and lack of experienced politicians running committees and the like. experience/age are positives as well
