Most (I assume) Trump supporters know all that. Will Trump be able to make good on all his promises? Who knows. It does not matter at this time and place.
What matter is that Trump is giving the “silent majority” a voice. He is allowing Americans to stand up and be counted. His supporters do not want illegal aliens coming and staying in this country. His supporters want these same illegals sent home. His supporters want the wall built. His supporters do not want terrorist invited into our nation (and since we can not tell by looking, and since most world terrorist is based on Muslims, then yes, we do not want more Muslims let into our country.
His supporters are tired of POLITICAL CORRECTNESS, the laws against free speech, and free association.
In other words his supporters do not like the direction our leaders have been taking us.
Until he came onto the political stage, none of these issues were being discussed nor would they.
So support for Trump is more than support for the man, it is for the things he is talking about.
Even if he loses, the politicians will know that the people are very angry at them as this time.
We can’t just be angry at them we need to HURT them badly by getting those who need to be tossed from office, tossed. We need to get those FIRED who need to be Fired, fired. And when the MSM comes screaming about how can Trump fire lifelong Dem operatives/bureaucrats, Trump will tell Dem all to go EF themselves! But that’s just my thoughts on the matter.
