Liberals rejoiced when Michele Bachmann announced her intention to retire from Congress at the end of 2014. Bachmann will no longer be around to carry the tea party banner in Congress. But she's almost guaranteed to be replaced by another far-right conservative. Minnesota's 6th District skews heavily Republican -- voting 56 percent for Romney in 2012. Whichever GOPer emerges from the primary should easily waltz to a general election win in November. And that successor could either be a Bachmann clone or Minnesota's own version of Grover Norquist.
