I think a lot of people oversimplify even how they talk about this, and it confuses their conclusions.
It’s not really true that a political party that wants to win more votes, decides to “move left” or to “move right.” That’s more what commentators and other observers say about it.
What actually USUALLY happens, is that their leadership takes a look at what various voting blocks appear to want or to dislike, and then they tailor their party message to try to grab the votes of that block, while still pursuing at least a GENERAL version of their original goals. Onlookers might SAY that the party is “tacking right” or “tacking left,” but really, that’s never actually the case.
The thing is, in order to gain controlling power in the US, a party has to figure out how to KEEP the people that they already have in positions of influence, and then ADD to them. If the party suddenly dumps everything it stood for on the previous election and shifts to the other end of the spectrum, they will LOSE a lot of their existing people.
So. Defeat NEITHER causes a party to radicalize, NOR does is cause a party to moderate. It only causes a party leadership, to try a different approach to tempting voters to choose their side.
The nation as a whole, ALSO doesn’t suddenly shift from one point of view to the other. People didn’t become vastly more liberal in the 1960’s, or swing to being vastly more conservative in the 1980’s. They didn’t vote FOR Obama because they suddenly became less racist, nor did they vote for Trump because they suddenly became MORE racist.
The reason why the Republicans may have SEEMED to move right at various times, is because the potential voting blocks that they saw as up for grabs (i.e. being discarded by the Democrats), were all rather right-ish looking.
Abortion itself, for example, isn’t either a right or left wing thing. People on both ends of the spectrum as well as all sorts of people in the middle, don’t positively LIKE the idea of it. What leads it to SEEM to be a right or left wing issue, is what people want to do about it, and how.
By all logic, Republicans SHOULD be the party that supports “choice,” and the party that supports marriage equality, because they make so many righteous pronunciations in opposition to government intrusion into private concerns. But instead, they completely discard those supposed “core values,” because they saw that the Democrats had discarded the large number of people who want government to RESTRICT everyone’s individual rights in that area.
The same thing is true about Health care. By all logic, the GOP SHOULD be the party that favors universal coverage, and government funded health care, both because it’s much more efficient, and because it would remove the financial burden of health care from employers and businesses, so that they could more easily compete with foreign interests.
But they didn’t, because they have a long heritage of opposing anything that was first supported by traditional Democratic groups, such a labor unions.
Trump IS certainly an anomaly election, in more than one way. But then it’s true that most of the latest Presidents we’ve had, have been anomalous in a way. Clinton won reelection despite being caught screwing around on his wife, and was popular despite a successful impeachment. Bush junior won twice, despite being disliked for the mess in the middle east. Obama won despite racism, more because everyone was so angry at the Republicans for the economic collapse of 2005, that they would have voted for pretty much any THING that ran against them.
And aside from the people who refuse to accept facts, Trump’s victory was assuredly NOT a mandate for anything. He also won by being AGAINST things, rather than by being for anything concrete. Hence his odd reverse margin of victory.
And by the way, adeher is entirely off the mark with his post saying " Yeah, Democrats want single payer now and no immigration enforcement. They’ve actually left European left-wing parties in the dust." There’s zero evidence to support either assertion. A joke post perhaps?
