Whether a person is pro life or not isn't important. If the goal is to change the law of the land via the USSC, it doesn't even matter if the proposed Justice is pro life or not.
A person can be pro life or pro abortion and still recognize the Roe decision as a bad one. The personal opinion shouldn't matter.
From the personal opinions, one can also get insight into their ethical character or read into their way of thinking or reasoning.
Many folks who do believe in abortion do think roe was decided incorrectly, but would they as an executive try and overturn roe, would they veto or oppose partial birth abortion bans?
Would the support or oppose parental notification?
And the reasoning behind their personal opinions can also tell you if they are being genuine or if they are simply spitting out what they think the public wants to hear.
No matter who is the GOP nominee, if they are not pro-life and they are not pro-2nd amendment, I will not vote for them.
