Republicans are about to come under pressure to keep their promise to repeal Obamacare, the New York Times reports, highlighting a coming campaign backed by the Koch brothers and their allies. The key quote from Tim Phillips, president of Americans for Prosperity, which is coordinating the effort:

Why this matters: Initial spending is just in the "low six-figures" the NYT reports, but this could be a sign of pressures to come for Republicans as the Obamacare repeal (and replace) effort seems to have stalled in Congress. As the Times puts it: "this early rift between the party's activist wing and its leadership in Washington could be a taste of what Republicans can expect now that they control the government entirely and are no longer able to blame Democrats for blocking their agenda."
