Yes. Quite simply, yes it is.
There really is no logical, rational, honest way to argue that they aren't. The entire Republican Party. Whole kit and matching kaboodle.
They are fully supporting an unimaginably despicable man as their presidential candidate, seemingly without the slightest conscious thought of there being anything wrong with that. The Republican Party's voters are in the majority in choosing him as their party's presidential candidate in nearly every single state primary so far. These voters will, by all objective observation, excuse him any despicable thing he has ever done, is doing, or ever does. It is simply what we have watched and fully witnessed them doing. These are despicable actions.
How could it be accurately and honesty said that this doesn't make them despicably despicable in their despicable complicity with their despicable leader's despicableness?
Their Chosen Despicable One calling fellow human beings in the most dire straights of their tragic lives "animals" barely gets the needle moving on their Despicable Meter...
Stoking racist outrage and hatred toward fellow human beings over the most vile and despicable lies about them...
Inciting his most violent followers with promises of "bloodbaths" to emerge if he isn't elected apparently isn't despicable to these despicable people.
Lying his fuckingass off to any terrified level of desperation he is cornered into lying certainly isn't "despicable" to them. They love his despicable lies even knowing that they are lies.
Stealing top secret documents and trying to hide them when asked over and over for them back may be a lot of terrible things, but I guess despicable isn't one of them.
Being an indicted felon for a cacophony of crimes who has yet to be tried only because his cronies already partially infect our Justice system and he's playing it all for time is just the actions of an innocent man to them. Nothing despicable there.
Raping women, libeling innocent people, stealing from various charities, genuflecting to every tyrannical dictator he encounters, egging on the hanging of his vice president, and a violent overthrow of the Constitution, our Justice system, and very democratic form of government that has stood into its third century... Unfathomably, none of it rises to the level of despicable for them.
Nothing he does is despicable to Republicans because admitting his despicableness is also admitting to their despicable own despicableness for facilitating, condoning, empowering, supporting, defending, and ignoring his despicableness.
But he is quite despicable to rational, patriotic American citizens. Rest assured: The entire Republican Party has become entirely despicable. There really is no two ways about it.
