Trump is widely disliked. Rolling in the mud with him helps only that pig.
Might feel fun to see a Dem “punch back” but, believe me, keeping your shirt clean is the only way.

When you try to defeat their smears by clapping back and pleading your case, the public only sees two people fighting.
Mudfights favor only the pig.
