Behind Bachmann's decision not to seek re-election

The Daily Circuit talks to Politico reporter Alex Isenstadt about Rep. Michele Bachmann's decision to end her Congressional run after four terms. Earlier this week Isenstadt wrote about the difficulties Bachmann would have faced in a re-election bid. Excerpt:

Minnesota Rep. Michele Bachmann may be the congresswoman with nine lives. But 2014 could be the gravest threat to her political career yet.

The bomb-throwing conservative and onetime Republican presidential candidate is girding for what promises to be a ferocious reelection contest. Awaiting Bachmann is a serious Democratic opponent who has the full backing of his national party and a suburban Twin Cities electorate that six months ago nearly tossed her out of office.
