It's the party of the angry white guy... and Yang. And since Yang likes to flex its macho muscles with talk about power, greatness, and, of course, the all-mighty gun (and that means massive gun/fire power), it favors war. This is wounded manhood turned into a plight against humanity.
The Dem party had a tradition of speaking to labor/unions, women, Blacks, and those left outside of the "white boy tent." In a very real way, it's Yin to the Republican Yang.
As many realize, with Big Money and its Shadow Elite players coming to control media, election campaigns (and outcomes), courts, congress, and the increasingly corporately controlled world of commerce operating on all levels (what with big banks swallowing little ones, as Walmart essentially does likewise to so many mom and pop small business operations), the political process has also been subsumed by Big Money. It forces ALL candidates to cater to Big Money donors and in the process, sell out. Thus, both parties come to serve Big Money. Repugs may get the Defense Firms while Dems get Wall St. Ultimately, mammon and Mars work in cahoots to support the empire's use of force in pursuit of global assets and hostile acquisitions.
Many who comment here (along with a good number of conventional media pundits) focus on the INDIVIDUAL sellout. This is either naïve or tactical. If naïve, it conveniently loses sight of the full scale of Big Money bearing down on elections, candidates, and therefore all possible outcomes. If tactical, then the emphasis on the "bad apple" allows the systemic fraud that U.S. elections have become to remain largely unexamined. THAT protocol is used to preserve corruption in every system ranging from major banking fraud (toss out one scapegoat), to torture inside the military (link it to a few "bad apples,"), to police brutality (if possible, blame the victim), to each successive shooting (blame it on the person's mental state), to each successive oil spill (look for "what went wrong" THAT time), etc.
This focus on minutiae and/or the single Bad Player is a strategic way for elites to maintain systems that are massively corrupted and punish far too many persons and living beings at every phase of their toxic operations.
