Ayn Rand, in her Ayn Rand Letter to her strongest supporters, told them early in 1976 to reject Reagan in favor of Ford because Reagan was an enemy of abortion which, given her own "lifestyle" of endless serial adultery, seemed like an essential "right" of some sort.
Reagan annually addressed (by telephone hookup) Nellie Gray's Pro-life marches on each anniversariy of Roe vs. Wade during his presidency and even authored a book on the subject: Abortion and the Conscience of the Nation (1983) undoubtedly angering Nancy and the quislings like James Baker, Howard Baker, Michael Deaver, et al., who were always determined not to allow Reagan to be Reagan. He defied them on abortion and at Reykjavik among other occasions.
Romney has NEVER been a pro-lifer in his entire useless life. He is the living embodiment of what Reagan called "pale pastels" not needed in the GOP's banner. He is also a serial liar on most issues that count and bad on all of them.
I don't know where you get the notion that Romney has ever "signed legislation against pro-abortion." I don't suppose you have any facts to back up that editorial opinion.
Two years after (2006 vs. 2004) he CLAIMED to have become "pro-life" Romney did include Planned Barrenhood on the board of Romneycare permanently and made abortions, however complicated, available to all under Romneycare for a mere $50 co-pay. He has yet to publicly repent any provision of Romneycare much less its entrenchment of subsidized abortion on demand for all comers subsidized by each and every citizen of the Commonwealth of Massachusetts via insurance premiums. His successor, Governor Coupe DeVal, has gotten rid of the $50 co-pay.
With the sorry likes of McConnell and Cornyn as Senate GOP leaders and the even worse spineless moneygrubbers Boehner, Cantor and McCarthy running the House, try not to hallucinate that the monarchist GOP-E types will do ANYTHING to write useful legislation without permission from Romney and the Wall Street plutocrats. There would be no similarity whatsoever between a putative President Etch-a-Sketch and Dubya much less Ronaldus Maximus on the pro-life issue. Also, Dubya's mommy (Barbara Bush), and his paternal grandmother (Dorothy Walker Bush) are/were inveterate and unrepentant pro-aborts and so Dubya was overcoming his background to be a pro-lifer and did quite well. In fact Dorothy Walker Bush was for decades a member of the national board of directors of Planned Barrenhood. Romney, to the extent that one may view him through a prism as a Mormon, overcomes his background as well since Mormons are, unlike Mittler, generally reliable pro-lifers.
On what has Chief Justice John Roberts directly betrayed pro-lifers as to abortion??? Calling the "premiums" for Obozocare a "tax" is not such a betrayal although conservatives certainly expected better of him.
Excellent overview.
You're in trouble now. Ayn Rand is a heroine among some here, Godless atheist that she was.
