Minnesota Republican Michele Bachmann began her fourth term in Congress Thursday by immediately filing another bill to repeal the Affordable Care Act "in its entirety." There was no press announcement. Nor was it mentioned in a swearing-in day press release announcing staff changes, office locations, and a new Web site design. The news came via her Twitter account: "At noon today, I introduced the first bill of the 113th Congress to repeal Obamacare in its entirety." The GOP-controlled House passed repeal legislation in the last session of Congress, though it wasn't the version authored by Bachmann, who often describes herself as the "tip of the spear" in the repeal effort. In any case, the bill never went anywhere in the Democratic-controlled Senate. On the presidential campaign trail in 2011, Bachmann often told audiences in Iowa that defeating President Obama was the last best chance of undoing his signature health care law. But that doesn't mean she won't keep trying.
