Can We Vote Pro Choice If Pro Life Candidates Are Going To Lose?

[KarenJoanna]

 

Elections are coming up and I found a christian website with recommendations. On this site they voted for some that were pro choice because they said that the other candidates while being pro life, were not likely to win so they recommended to vote for the popular candidate that is the lesser of 2 evils. Can Catholics vote for these candidates even if there are other pro life candidates but they are less likely to win the election? Sometimes it is pretty obvious who is going to lose so would that be an excuse to vote pro choice? Would it be a sin?
