Premise indicator - if, because
conclusion indicator - therefore, for this reason

premise- one is a liar in hihs private life, one should never vote for someone who will lie in public office
sub-conclusion - one is a liar in his private life, he will also be a liar in his public life
conclusion - one should never vote for a political candidate who has been known to be deceptive in his personal life

are these correct? would the first sentence of the paragraph also be a premise?
also not sure what the component statements are

Im not familiar with such things
However the last part
"One should Nenner vote for someone who will lie" is not causally connected by any arguments before

If a) honesty is a virtue and b ) virtuos behavior transcends in every life's aspect
Then if you are not honest (e.g) you lie this will also transcend in every day
(Which right there is not causally linked, because if a Is true doesn't mean the opposite is false)
If you should never vote for a liar (in public) then you should not vote for someone who has been lieing (in private)

That seems the logical structure to me regardless of the "because and therefore)
