Disregarding moral arguments, politics wise, is it better that Trumpcare passes?

First the passage is Trump means thousands of Americans die and millions lose security. It would be bad.

That said, the harm this bill will cause will destroy populations in rural America and his core supporters. Seems likely that is will erode support and could result in a landslide in 2018. Remember, millions will be losing coverage right before the mid-term. The political environment seems to be swinging towards dems. With all that, politics wise, does the GOP passing the bill help dems?
