The Republicans had their own versions of "healthcare reform" during the time that Obamacare was enacted. They offered one as legislation and the Dems refused to consider it as an option, then they forced Obamacare through against the wishes of the American people.

Claiming that Romney said he wants to keep parts of Obamacare based on this David Gregory interview is equivalent to talking out of one's ass. Like Newsmax, constantly.
I had a very liberal sociology professor at the time and had to eventually use some creative phrasing to keep my GPA up to snuff, because he’s a liberal soc professor at a community college so no one is surprised that anything that hinted at a conservative approach could be allowed past the threshold. I worded a paper with such subtly sarcastic stabs at socialized medicine that it was too much like a glowing recommendation and I hope it will never be found again.
He kept referring to it as healthcare reform, everyone did, and it is the version of healthcare reform that passed. I know that the Republicans had their own versions (and have had their own versions for awhile) but that’s the one that passed.
Because that’s the one that passed, that’s the one that Romney’s talking about when he says he would keep some aspects of it. This is old news anyway, we know what his own plan involves. But, he worded things in a way that allows for some wiggle room on exactly what of those two parts he would keep. Like I said before, he had to support those two aspects. You can’t really win the presidency with a quote of “Yep, I want people with pre-existing conditions and college students under 26 to not have guaranteed access to health insurance.”
