You asked why the Porn Star boning was a newsworthy item.
It's pretty simple, mainly because he denied it. Secondly because he ruthlessly attacked Hillary for Bill's affairs, again playing the morality card.
From 2016:
“Hillary Clinton was married to the single greatest abuser of women in the history of politics,” Trump said Friday in an
interview with the New York Times, referring to former President Bill Clinton. “Hillary was an enabler, and she attacked the women who Bill Clinton mistreated afterward. I think it’s a serious problem for them, and it’s something that I’m considering talking about more in the near future.”
Thirdly he was running for the highest office in the land and was busted lying about it while smearing her, just like you did in your post (as if it justifies things) which is what irrelevant.
The rub was he was attacking character, in a party that has always tried to cloak itself in religious morality instead of the separation of church and state...and he was busted in a lie with a huge morality scandal.
The reason why Trump drives Dems insane has very little to do with policy (which is mainly idiotic and more based on righteous morality fear), it's more to do because he's taken over the republican party with having zero accountability other than Dems (which piss us off because the party should be handling him, but you haven't either out of fear or out of aggreance).
Trump must believe that America was great in the 1950's and wants to go back there, but not in an enlightened Eisenhower mindset, but a darker one with extreme nationalistic preferences (there's a reason why every Nazi/white supremacist actively support him).
Still that's not the biggest reason why he drives Dems crazy.
It's because he has manipulated his base into an extremely dangerous spot to the point that he can say and do anything and they'll follow and support. It doesn't matter how obvious the lie, they'll believe him. He's made his supporters conspiracy theory zealots that only believe Trump.
Anyone who testifies against Trump from his inner circle is simply branded an extortionist.
Any media that goes against Trump is simply fake news with a massive grudge. Simply a media witch hunt, because Trump determines what news is real or fake.
It's allowed him to lie about anything, to make up whatever narrative he wants and his followers never question.
As Aloha said, it's a cult, and a dangerous one that is causing major damage to our society.
So yeah, that's why he drives Dems crazy. It's not Trump, it's that his followers let's Trump do and say whatever he wants with zero accountability or even an acknowledgement of 'that's f'd up' or 'I'm calling BS here'.
That's frightening to be honest.
