Here are some vows which have been in the news recently.
(1) Donald Trump is being criticized for "revoking a vow" to support another GOP nominee. You can read about it here:
(2) Bill Clinton repeatedly broke his marriage vows, but Hillary thinks that's funny. You can read about it here:
(3) Obama ad-Dajjal treats his oath of office as if it were some kind of joke. The presidential oath specifies that he "faithfully execute" his office, which includes the requirement "he shall take Care that the Laws be faithfully executed". Clearly he has not done this.
Which of these vows really matters?
Does it matter that Trump no longer wishes to be screwed by a party which obviously does not want him? Not to me.
Hillary obviously does not give a damn about fidelity, either to vows or to our nation's laws and regulations. Does that matter? You're damn right it does.
Everything Obama ad-Dajjal has done is a mockery of the presidency and our nation. He broke his promises and violated his oath of office. Do you want 4 to 8 more years of that kind of crap? I don't.
Breaking one's oath of office should be grounds for impeachment.
