People change there minds. Reagan did it, others will as well.
With Reagan, it was all about the historical context and content. Its about reaching a principled decision and sticking to your principles. Its not about changing your mind when it suits your fancy, or the changing political winds. The situation with Romney and his fluid position on the abortion issue is not the same set of circumstances and factors that highlighted the Reagan case.
Reagan clearly did not favor abortion on demand, personally or as a matter of public policy. He reluctantly signed a bill that relaxed an outright ban to allow for the exceptions of rape, incest, and to save the life or health of the mother, and he was correctly troubled by the "health" exception. He almost immediately labeled signing that bill a mistake.
As Fred Barnes wrote just after Reagan's death:
"Within a year after signing the abortion bill, Mr. Reagan told political writer Lou Cannon that he'd never have done so if he'd been more experienced in office. It was 'the only time as governor or president that Reagan acknowledged a mistake on major legislation,' Mr. Cannon writes in his new book, 'Governor Reagan: His Rise to Power.'"
If Romney will admit he changed his mind, that would mean something.
People do change their mind, nothing wrong with that.
But he's not. His claim is that he was never "pro-choice" even though he stated ABORTION SHOULD REMAIN LEGAL!
It's a Clintonian claim of the worst sort.
