Yeah I missed that show, although I've heard it was very good, but anyway, OK I think I get it. You seem to be clarifying that its not your view that Trump is worse (or better from the perspective of his supporters) than the other Republicans. You think he's the same level of bad, but Republican voters and/or Trump supporters think that Trump is better (ie worse from the Democratic/progressive perspective).If you know the context of the reference it makes more sense. In the original show Jesse tells the cops that because they arrogantly believe they can easily deal with Walt; what instead ends up happening is that Walt goes free while the cops both are killed by a gang of Nazis. I'm not using the quote to refer to the level of evil that Trump has, but rather to his evident dark powers that he uses to bamboozle his political enemies.
The Democrats have some chance against it because they appeal to completely different values. Trump's republican rivals have to play on the same field he plays on, and so they end up seeming like lame versions of him.
If that's right, then it seems like the reason you believe Trump's supporters think he is awesome and the other Republicans are lame wannabes, is because of Trump's superior ability to court them through his schtick and antics and less dog-whistle'y, more direct appeals to their prejudices, biases, fears, bigotry, etc.
If that's also right, then I will suggest to you that this is precisely one of the reasons that Trump is in-fact worse. As @Gori the Grey points out, there are millions of Republican voters that will only show up to the polls for Trump. Now of course as Gori also touched upon, there is the converse question of how much Trump's absence from the election might depress Democratic turnout. But then we're drifting into the "hoping the worse opposing candidate wins so we can beat them" mentality, which is trash.
