Weeks after brokering the compromise that helped the House pass its healthcare reform bill, Rep. Tom MacArthur, R-N.J., has resigned as co-chairman of the centrist Republican Tuesday Group. And it appears that he was forced out of the position by discontented members of the group or at least felt so much pressure that he didn't have much of a choice.

Between the lines of his even-keeled comments on his own ouster, there's a very bitter-sounding jab:

"Clearly, our group is divided. Many in the Tuesday Group are eager to live up to our ideal of being problem-solvers, while others seem unwilling to compromise."

It's anyone's guess how the Obamacare repeal debate will be resolved, whether Trump will ever get to sign a bill or how voters will react to the repeal bill if it does indeed become law. But MacArthur's willingness to make a deal called the bluff of a lot of moderate Republicans who had again and again promised to repeal Obamacare and who had voted to repeal it when it didn't count. When they tried to go back on their word and defended Obamacare when the chips were down, he put them in an awkward position. However you feel about the final bill, he deserves some applause for that.
