Kennedy-tough man,no scrupples-was a good president and probaly would have been a great one if he would have lived longer.
Johnson-May have been a very good president if he hadn't been saddled with the war
Nixon,Very effective,would have been considered with the best if not for watergate.Totally void of a concience.Makes for a great leader.
Ford-pretty much of a joke.
Carter-extremly inelligent,Too big of a heart to be a good president.Could not make the tough descions.
Regan-effective due to a very strong cabinet.Not the brightest of men.And at the end did not have all odf his faculties.Still very effective.
George Sr.-Did a decent job.Would probably have been reelected if he did not align himself with the extreme right.I believe in my heart,he was a moderate and would have continued to be if re-elected.He aligned himself with the wrong people and lost the woman vote and hence the election.
Clinton-another who was void of scrupples and hence an effective President.
Jr-not very bright.seems to be lead around by his cabinet who seem to be power hungry and very dangerous.Time will tell what his term/terms will yield.
My slant on the presidency-to begin with you have to be a certain breed of person to even want the job to begin with.You need more balls than conscience.You have to be calculated,cold blooded and ruthless to be effective.Just my take.
So most effective in my lifetime? Nixon followed by Clinton.
Least-Ford,followed by Carter.
