If there’s one thing that Republicans can agree on, it’s tax cuts. On lower taxes, there are no regional disagreements, no ideological dissenters, no schismatics jockeying for control of the party. On taxes, Republicans all sing from the same hymnbook written by the sainted Reagan, in broad harmony.

Why, then, do their stumbling efforts on taxes look so eerily like the shambolic process of repealing and replacing Obamacare? Why does it seem so possible that the whole thing is going to end the same way: with Republicans slinking away in defeat from one of their core campaign promises?
