But McCarthy went too far when he went after the Army and even accused Ike of being a Commie, he went full MTG on Eisenhower.
In the end, he did more harm than good.
I should point out that, it was General Marshall that McCarthy went after (who was the Secretary of State when we "Lost China") He didn't accuse Marshall of being a Communist directly, but inferred so strongly that his actions were serving the interests not of the American Citizenry but of other interests around the globe, that the accusation was made.

As for Eisenhower, I lost respect for him as well. He was part of what we would call today the "Deep State", and he went after McCarthy as well, because he thought problems of Communist infiltration of our government should have been handled by...the government. But he and his administration did what all Deep State governments do-he did nothing, absolutely nothing about it. It was far more important to protect the appearance of the American Government of which Eisenhower was the leader when he became President. If you look at Eisenhower's record in the military, it was to protect the Army against all criticism. He believed, and became intractable when it was attacked politically. So, he and his administration finished the job started by Roosevelt and Truman, and swept it all under the rug.
And in the end, he did far more good than harm.
McCarthy rang the bell about Communists in the government WHEN NOBODY ELSE WAS DOING IT, and paid for it with his reputation and eventually, his health when the government was weaponized against him in conjunction with a hostile media.
Before McCarthy arrived on the scene in conjunction with the preceding HUAC which McCarthy had nothing to do with, Americans viewed their fellow Americans who dabbled in Communism as eccentrics, prone to harmless youthful political explorations which were largely viewed with a degree of tolerance, in the full expectation that they would "grow out of it". After McCarthy took his stand, it became publicly disreputable to associate with or dabble in Communism. That gave us 10-20 years to set things right, and it isn't McCarthy's fault that people and our own government didn't listen to him. Leftists and Marxists of all stripes began to ooze into the public light in the late Sixties and early Seventies, where it lost the stigma. Look where we are today. We have open Marxists at all levels of our governments, Federal, State, and Local, and none of them are stigmatized for it. Obama was an open Marxist and proud of it.
It isn't McCarthy's fault. He took the bullet for ringing the bell. I venerate him for doing just that. And I wholly disagree that McCarthy was anything comparable to Marjorie Taylor Greene. She is nothing compared to him.
