I don't consider the "Trump was a democrat" argument a valid one to excuse current demonrats. Democrats back then were nothing like the rabid leftists who comprise a fair amount of the current demonrat party, for starters - while the 3-letters have devolved into a malevolent force for evil.

Trump maintains relationships with all kinds of individuals. Perhaps you've heard of the old adage "Keep your friends close and your enemies closer"? George Jr and Daddy Bush were "fairly consistent" about claiming to have the American people's best interest at heart. There's a danger in taking these people with questionable ties at face value.

I simply think caution is advisable. MHO.
