Abortion has remained legal since the Supreme Court declared it is, but that doesn't mean you can say Republicans don't want to make it illegal, just because they haven't been able to yet. You need to look at more - that they have won elections by running against it, appointed judges who are against it, and expressed their support for ending it.
That's not the same as the social spending, because Republicans are often much more duplicitous in what they'll admit about their intentions, but you can easily identify their interests and agenda that often is at odds with what they'll admit publicly. And they have won many elections by running against those programs when it's politically viable to do so. In your recounting you ignore things from Clinton's slashing of welfare to the increases with programs such as Head Start and CHIPS.
You love to just ignore what you are told and respond repeating yourself ignoring the response you got, as you did again here when told that Republicans like Nixon have done 'liberal' things that are politically popular because of what they can get away with - as the example you ignored of Republicans LOVING unions under Eisenhower showed. Nixon did things to get popular support that he did not necessarily support. And Keynesian is not the same thing as supporting social programs - they may or may not overlap.
