JFK was the last honorable, decent Democrat, and the other Democrats killed him for it.
The Party of JFK is extinct.
JFK had his moral terpitude issues though but his presidential policies and actions were pretty darn good. Lyndon Johnson not so much. I liked Carter and thought him a good, decent man but he was a god awful President. Clinton, like Kennedy, had his moral terpitude issues and if he initially was not a good President, Newt Gingrich and his reformer Republicans and Tim Penny (D) and his 30+ conservative old guard Democrats were able to drag Clinton into tax and welfare reform that was good and saved his presidency. He tried to resist Congress but eventually, as he had few convictions, he went along to get along.
Unfortunately those GOP reformers and good old guard Democrats term limited themselves out and were replaced by mostly leftwing extremists aided an abetted by a deep state that does not have America's best interests at heart. Thus Obama was a very lackluster and ineffective President, though not as bad as Carter, and Biden is just a mentally challenged marionette directed, scripted, and manipulated by deep state operatives with pretty much universal bad results.
And that is why I can support ANY Republican over anybody the current Democrats will put up other than maybe Kennedy Jr. who might be better than a far leftist anti-American Republican. But Kennedy is too old guard, too common sense, too pro-America so they'll pretty much destroy him. And a Democrat President, no matter how good and capable, will still have to work with a corrupt and anti-American congress that pushes very bad policy.
So unless we nominate and elect a reasonably competent Republican, whoever that might be, we're pretty much screwed. And we must give that person a GOP congress or he/she won't be able to do much to fix the mess we are now in.
