It is a lot to handle. If you scroll down to the topic I listed, it is pretty clear. The big confusing thing is they put R/D/I graphs on the left and put Democratic-leaning / Republican-leaning on the right. It gives you more information than you might want, but you can see how the different generations identify with a Party, and also how the Independents are leaning.
My take-away is that the Republicans are doomed unless the "growing more conservative" thing is faster than people age. When you throw in the effects of the coming non-White majority, it's obvious. Republicans are hanging on by a thread by gerrymandering, voter suppression, and packing the courts. But those won't be enough.
