We always knew putrid putin was PRO the dumb cluck duck. WHY IS IRAN? Because the dumb cluck duck is so dumb? What does Iran get out of him?

LOL. Iran is not pro-Trump.

Threatening voters does not help the candidate doing the threatening.   It makes people determined to go vote against that person. 

Iran thinks less of him than many Americans.  he's bad mouthed on numerous occasions (right or wrong, calling names isn't diplomatic).  he even tried to start a war with them (and they us).

I also haven't found any media coverage of Iran "liking" Trump.

In fact, I would say they dislike him more than most nations do - as he unilaterally took the US out of the arms agreement, and then tried to intimidate other nations to violate the accords and impose additional sanctions on Iran.  He also tried to intimidate them to disregard Iran's compliance with the agreement and "roll back" the sanctions to the start.  

Even the "man on the street" of Iran, who generally see US/European sanctions against their leaders as deserved, fail to understand why Trump left the accord - as it hurts them more than the Iranian leadership.
