Nuns Getting Political In Wisconsin

From Brietbart.com:
The nuns who have circulated and signed petitions include sisters from convents and other Catholic institutions across the state. 
Over 100 signatures, for example, all of female voters, as verified through iverifytherecall.com, list the same address as a Dominican institution in Sinsinawa, WI, in the southwestern portion of the state. Representatives of that organization could not be reached for comment. 
One Catholic official at a school with a large number of signatories stressed that Catholic organizations advocate for the poor and downtrodden, but do not take political positions, and that what their individual members do is up to them alone. 
Though many Catholic voters support Walker, and roughly 40% of Wisconsin Republican primary voters are Catholic, there is some Catholic opposition to Walker's collective bargaining reforms among those partial to the "social justice" movement within the Catholic Church. Democrats are hoping to tap into that opposition.
Walker's most likely Democratic challenger, former congressman and former Milwaukee mayor Tom Barrett, is a practicing Catholic but has been criticized for opposing the ban on federal funding for abortion. Other Democratic candidates--Kathleen Falk, Doug LaFollette, and Kathleen Vinehout--appear to be pro-choice.

I am a Catholic and I really get tired of priests who preach politics in the pulpit.  And nuns who think they are than anybody else because they took a vow of poverty but yet are anti-Catholic.  It is clear that the political priests and nuns just don't like the Catholic Church and lack the common sense that God gave a goose.
Do the nuns have the legal right to sign the recall petitions? sure.  Do they have the moral right to do so?   I don't think so.
