1) You absolutely have a moral choice.  There's always a moral choice, and at no point can anyone's free will be violated to make an immoral choice.  But in this case, it's quite simple and requires nothing overly dramatic.  You can simply write in a candidate or refrain from voting.

2) One does not make decisions based upon "practicality" but upon the Catholic principles of moral theology.  That has to be one of the dumbest things you've ever posted.  If an action is immoral based upon Catholic moral principles, you may not do it regardless of "practical" considerations.

And you (and others here) will be held accountable for promoting that others commit mortal sin.

Encouraging others to vote for either Trump or hαɾɾιs may constitute a sin of omission, as both candidates hold positions that are pro-abortion, which stands in direct opposition to the teachings of the Catholic Church regarding the sanctity of life.

If we want to get technical, every (99%) Federal candidate for office (i.e. Congress, Senate, President, etc) has held that there are "exceptions" for pro-life and abortion (i.e. rape, incest).  These exceptions are in direct opposition to Catholic teaching.

So, to summarize, 99% of every Federally elected official (and a very high % of state/local officials too), since 1973 (i.e. Roe vs Wade start) has been anti-catholic.  Which means...if we want to get technical...anyone who has voted (at any time) since 1973, has committed a mortal sin, because you've voted for somebody that has held these anti-natural law exceptions.

If that's the logic you want to use, then voting is inherently a mortal sin (in America, at this time).

Absolutely, this "logic" is just Catholic reasoning. 

To use another analogy:  If your OBGYN tells you that he is anti-abortion, but you find out he endorses birth control, are you going to choose another doctor?  Perhaps you might find a doctor who does not endorse birth control - good luck with that!  Are you not going to shop at Walgreens or Walmart because they sell condoms?  If every grocery store in your neighborhood sells condoms - and they all do - are you going to just grow your own food?  Or are you forced to pick the lesser evil?  This grocery store does not support LGBTQ, even though they do sell condoms, so I will go with them.

Some of you on here, methinks, will not apply these principles to your own life, but you will apply them to the upcoming presidential race.

To piggyback off of your analogy. There is a burning schoolhouse full of children. If you do nothing, they are going to die.

the building is about to collapse. You can run in but you only have the strength to save one child. Do you run in and save one, or, because you can’t save them all, do you save none of them?

I know the analogy isn’t perfect but maybe it bears some ponderance.

children are dying by abortion on a daily basis. One candidate approves of some abortions, one candidate approves of all abortions. By voting for the candidate who approves of some abortions rather than the candidate who approves of all abortions, there will be less abortions taking place, moving us closer to the goal of zero abortions.

I know the analogy doesn’t totally apply to the 2024 election as Trump is also in favour of some other devious things. However I think the analogy is still a decent one.

Or more to the point:  I will be an election officer here in Jefferson Co. (Louisville) on Nov 5th.  Let us assume that I do not vote.  Am I committing a mortal sin by working as an election officer, assuming that 90% of the people will vote for either Trump or Kamala.
