LoL, are you saying WV is the only people that pay Manchin? His top donations this cycle are from businesses that stand to gain by this measure not passing (see OpenSecrets.org, etc).
Edit: This isnt to say the measure not passing is all his fault. Im way tired of all bill passing on party lines, however, its disingenuous to pretend Manchins motives are mostly for the people actually picking the coal out of the ground for him.
