Yes, it does work when calling out DP posters who won't admit that their TDS for this president is based on their politics.
Like I said, he is no more immoral and dishonest than the rest of our past presidents, at least in my lifetime.
Exception is Jimmy Carter though while honest sucked as a president. M/O.
Yes, again, he did it too! is one helluva defense. My parents always said, "Oh, good point. Never mind..." when I tried it, because what someone else did or might have done is a great defense for what I did. I'm pretty sure all parents adopt this same standard with their kids.
Somewhat more seriously, whether or not Nixon and Obama and Reagan and Bush I and II were overall more, or less, or exactly, precisely (your claim) just as immoral or dishonest as Trump is a ludicrous standard, because it's impossible to demonstrate objectively. Did they all lie - of course, in some way or another. Were they all precisely, exactly, just as immoral or dishonest as the others? Seems unlikely, but how have you determined that they are exactly, precisely, the same level of immoral and dishonest? How do you judge the serial adultery of Trump versus the non-existent adultery (that we know of) for Obama, Bush I and II? As to lies, where is the evaluation of all the public statements of each president and the evaluation of their lies versus those of every other President? Lying about big things is more serious than 'white' lies, so how did you weigh what was serious versus a 'white' lie? Does one big lie count roughly the same as 100 little ones, or do we disregard the little lies entirely? Etc.
More to the point, what you appear to be saying is that because all other Presidents are dishonest and immoral, that we cannot legitimately judge any Presidents truthfulness or dishonesty or morality, or object to their dishonesty and immorality, because "Mom, he did it TOO!"
It's pretty sad that's where some large part of the country has come to - it's unfair to have a standard of behavior for POTUS because every President fails that standard.
