Romneybots cannot defend the liberalism of the Romney family.
George was a liberal pro-abortion candidate for President, his wife was a liberal pro-abortion candidate for the Senate, Mitt is a liberal, pro-abortion candidate for President now.
Romney and George stormed off the convention floor to protest conservatism in 1964, Mitt has been fighting conservatism ever since.
We know that Lenore Romney, Mitt's mother came to favor more liberal abortion laws after a relative died in 1963 after an illegal abortion.
But it's not clear that she campaigned on the issue in her 1970 Senate race, and still less established that Mitt's father, George Romney, ran for President on a pro-abortion platform.
Remember that this was before Roe v. Wade nationalized and politicized the abortion issue. In those days when abortion was a matter for state governments, those days when Ronald Reagan signed a liberal abortion law, Presidents and US Senators wouldn't have had a say in laws pertaining to abortion.
