Yes, according to Rightosphere’s Kavon Nikrad, who asked Romney if he would repeal the individual mandate and the ban on exclusions for preexisting conditions:

I was one of the first in line to the book signing, and when my turn came I asked Gov. Romney if I could ask him a question. After he told me that this was OK, I posed the following question to him:
“You have stated your intention to spearhead the effort to repeal the ‘worst aspects’ of Obamacare, does this include the repeal of the individual mandate and pre-existing exclusion?”
The Governor’s answer:
“No.”
Gov. Romney went on to explain that he does not wish to repeal these aspects because of the deleterious effect it would have on those with pre-existing conditions in obtaining health insurance.

Second-hand to be sure, but if true, not a good sign for either Romney 2012 or the repeal effort.
