Ansel12 makes an excellent point that is lost on Cheney supporters. She's running in a GOP primary, in one of the most staunchly conservative states in the union. There's zero downsides to being publicly pro-life in a scenario like that. If her intent is to position herself as the "more conservative" candidate than Enzi and a "fighter" for conservative causes, she would have been vocally supportive of the pro-life position years ago, and probably even peppered her announcement speech with pro-life applause lines, knowing it would endear conservative GOP primary voters to her and perhaps get some hardcore pro-life Enzi supporters to consider her candidacy.
The fact she's always been completely silent on the issue and has avoided saying ANYTHING about it speaks volumes. Even if she's not pro-abortion, she certainly isn't comfortable bringing it up and thus can't be trusted to be as reliable as Enzi is on the issue.
When pro-lifers can’t even sense an intuitive “dog whistle” of pro-life in a prominent, many years publicly active, “conservative”, then I think we can conclude what is kind of obvious.
We don’t have to play stupid.
