False equivalencies: Hillary Clinton is NOT Mitt Romney
There are certainly some things to dislike about Hillary, but I actually think she was being refreshingly honest with the "basket of deplorables" comment. You sure can't tell from the worthless commentary of the worthless media, but it is important to understand the REAL differences.
Hillary was clear in stating that "deplorable" referred to racists and various other categories of bigots. That is, she was referring to people who hate other people, either for accidents of birth or for various acquired characteristics such as religious preference. She regarded it as deplorable that such people are eagerly supporting Trump, though I regard it as MORE deplorable that Trump welcomes their support. At this point, I am convinced the Donald is NOT faking it, and he really will do ANYTHING to become president, which includes accepting and even soliciting support from people who are deplorable or worse.
In contrast, Mitt's infamous 47% comment was really about HIS personal hatred towards roughly half of the entire population. He regarded those people as lazy bums who were never going to vote for a hard-working vulture capitalist. He was deploring their lack of HIS brand of greed, which is completely different from deploring their hatreds of other people.
I'm not sure where Romney got the exact value of 47%, but I can guess where Hillary got the "half", and even why she had to be fuzzy about it. The value depends on the exact question you ask. The question determines what kind of hatred you are measuring, and when such questions are put to Trump supporters the results range up to 70% picking the hate-filled response. Other questions elicit smaller percentages of "deplorable" responses, but "half" seems downright generous.
The latest poll shows about 40% of the voters supporting Trump, so the estimate of 20% of the voters as "deplorable" haters certainly is a lot of people. However, I think the standard of comparison here should be the percentages of voters who supported bad leaders in the past. Your political views probably don't matter as much as you think. If you deplore President Obama, then you think more than 50% of the voters made a terrible choice TWICE. If you adore Dubya, then you have to admit that more than 50% of the voters preferred Al Gore. (I'd even be curious if you have any rational and nonpartisan basis for attacking Obama, but I think I've seen all the criticisms and attacks by now, and many, perhaps most, of them qualify as deplorable.)
The original Republican Party led by Honest Abe was about constructive change (even though that led to an incredibly destructive war), and the GOP of Teddy and Ike was a party of gentlemen and their ladies. None of this applies to today's so-called Republicans led by Con Man Donald, the man of 3,500 suits, at least four major bankruptcies, and uncountable political bribes (but his tax returns would help count some of them).
