Not sure if he is what we need, but B16 should be given a chance.
Wuerl: Catholic legislators should make own decision on communion

From the little I know, he's more conservative than McCarrick (who was a disappointment). The statements in that article were made a year ago, and I believe that since then the Vatican has made some more specific statements on the issue of Catholic politicians who "disagree" with the Church but wish to publicly present themselves as Catholics in good standing. There has certainly been a lot more enforcement of prohibitions on pro-abortion speakers from various diocesan or college events, etc.
Maybe - one hopes - Wuerl will conform to the stricter Vatican position as time goes by.
I disagree with his stance, which may have arisen from being misled by Cdl. McCarrick, but he did use the opportunity to clarify some valuable Catholic teaching:
"And when a third asked why the church doesn't apply the same scrutiny to politicians who support the death penalty, Wuerl noted that the 2002 doctrinal note that clarified the Vatican's position on abortion does not call capital punishment intrinsically evil. The church opposes capital punishment, but mainly because the nation has the ability to incarcerate criminals rather than execute them.
"Still, Wuerl noted there were many areas where people fail to live up to church teachings, and that "it's the church's job to hold up those issues" for scrutiny, but the right to life is the primary issue facing the church today.
""There's nothing more basic than life itself," said Wuerl. "That's the reason for the intensity in this debate.""
