I think there's a huge difference between tweets with "promises and plans" (especially from before he was actually elected), and tweets saying "I have done this thing. I am doing this other thing."

It's reasonable to be cautious about a politician making a promise in anything but the most legally-binding possible way. It's not reasonable to straight-out call that politician a bald-faced liar if he hasn't demonstrated a propensity for such lies (unlike some I could easily name).
