She may have been persuaded that no one but Boehner had a chance, so she may as well vote for him.
She may have decided on her own, that she was elected by voters in HER district, not by the 10% of outspoken loud, but narrow representatives who offered the alternative path.
Her position is wise, intelligent, and does not tie her to a shrinking movement, which has failed to advance in 2012, failed in 2014 primaries and midterms, and again failed now in setting the playing field for the term.
A lot of this thing is about image. Online, associations, etc. To be associated with the rebel side is the same as that old "bad boy" image which some gals run to over and over.
James Dean and Marlon Brando once portrayed it. Middle aged women who went with the banker or accountant instead of the bad boys, look back with nostalgia, over the alternate path.
Fundraisers need imagery, so the rebel, the other path are used. Term like GOPe and Rino, repeated often enough take on meanings which often are false. In recent years we have witnessed political figures zoom from one identity to the other at near the speed of light.
Getting wound up by journalists and fundraisers and media entertainers serves their purposes, but not necessarily the purposes of sober minded steady work of government.
Nobody posting here today knows that Mia Loves voting constituency expected or wanted her to go and vote against Boehner. Projections would be only that they "think" they did.
Let her do the job for her district. I applaud her common sense, political maturity, etc.
