Is everything fair game if you're trying to win an election? Even lying about disaster relief?

It's not simply IQ; many people high IQs are foolish.  While everyone has the ability to think for themselves, many don't want to, as that would require effort on their part and they're not willing to put forth effort.  Many don't WANT to discern things to see whether they are the truth or a lie, as they only want things to fit their own point of view (no matter the cost).  

Many people are looking for someone else to blame and this need has been exploited very effectively. Everything from inflation to housing shortages, and the lies about disaster relief funds, has been caused by one group of people, according to certain politicians. 

You do have a point.

Yes, but there are times when politics should take a backseat to helping people recover from a disaster. To spread lies that the government won't help these victims only makes it so much worse for them. 

No sane person expects anything classy to come out of Trump's mouth.
