Doesn't really matter if Trump thinks grabbing whatever woman he wants, whenever he wants, is perfectly fine & legal. It's still assault even when the person is too dumb and/or deranged to see it. This is compounded by the numerous women that stepped forward and confirmed that behavior (even if some of them exaggerated or lied, it is doubtful all of them did, particularly with Trump himself boasting of such behavior - you'd expect there would be some aggrieved women out there)
It was just locker room talk. It's not his fault Billy Bush is terrible at small talk. Access Hollywood actually made me support Trump more because of its hilarity. Also, women love being taken furniture shopping.
Labelling something "locker room talk" doesn't change what it is. I've been in plenty of locker rooms and never heard that kind of talk. The ironic thing is, if it was some Muslim Sheikh saying this the right wingers would be all over it claiming Islam is anti-woman. But if it's a US president it's okay.
