I read a similar story off of Fox News, likely the same liberal writer, saying that the reason President H.W. Bush didn’t vote for President Trump is that he saw Trump’s Presidency would create or go down in “disaster”, causing violent economic upheaval, utter civil war with the immigrant stopping and security vetting, and possibly two major wars on the Chinese and Middle East fronts. The article also stated that the elder Bush didn’t believe that President Trump would finish out a “four-year or eight-year term” in Office, and also might only accomplish “less than four years in Office”.
GHW Bush did not want his plans to turn the USA into North Mexico interrupted.
That is the real reason.
The GOP has run only amnesty candidates since the last amnesty to block the citizens from stopping the illegal alien inundation.
