A Republican-backed plan to divert some defense spending cuts to domestic programs passed by a narrow margin Thursday evening, perhaps an ominous sign for Republicans hoping to pass House Speaker John Boehner’s plan to raise taxes on millionaires later in the evening.

 The bill passed 215 to 209, with one member, Rep. Bob Bishop (R-Utah), voting present.

 The measure passed despite warnings earlier Thursday from the conservative Club for Growth, which voiced strong opposition to the plan. The anti-tax group said it opposed the bill because “House leaders are refusing to make all of the necessary spending cuts now and instead are promising to make the cuts in a future Congress.”
