Two thoughts as I am in the inquiry phase for the diaconate.
One is you are allowed to hold political office since a deacon is of the people. Remember, however, that your calling to the diaconate will take considerable time, and the Bishop you serve (a deacon is not necessarily assigned to a parish) may have (name removed by moderator)ut into your political undertakings if it interferes with your ordained duties. Check with your diocese.
Second is that your wife does not have to be Catholic, but it may take a dispensation from Rome. We just went through a survey of “impediments” - things that could prevent someone from being a deacon. Mixed faith marriages were mentioned, but did not rule anyone out directly; frankly, I did not pay much attention to that part, but you can call your diocesan judicial vicar to find out. In our diocese, and I think everywhere, your wife must sign a consent for you to be ordained. If she does not agree, it will not happen. You will not succeed without her.
Also remember that if she dies once you are ordained, you cannot remarry. Many wives have an issue with this, more than the men it seems.
God bless, good luck.
