This is one of the really brilliant things the GOP has done. They've led us all to believe that it's just McConnell and a couple of other shitbags but that the rest of the Republicans are mostly OK.
That's a deliberate smokescreen. Notice that the "handful of Republicans" always happen to be in red strongholds? McConnell volunteers to be the public face of the GOP's bad policies because they know his seat is secure. Meanwhile, all the other GOP Congresspeople who support those same awful policies but might risk losing an election can stay out of the news and pretend it's not their doing.
McConnell was voted into his seat by a majority of the GOP Senators. They all know what they're doing.
Even so, D and R are both beholden to the American aristocratic wealth class for support, legitimacy, and power, so there is effectively no difference beyond a few, token, mild progressives in D who don't hold sway over the majority of neoliberals.
