Their strategy this session from what I can tell, and from what I heard on cable TV, is to try to lay low and not draw (any more Negative) attention to themselves, to try to not lose more seats in November.
So they sit and wait till Reid acts and then they respond to whatever he passes.
Of course this leaves them with a complete vaccum of purpose for being in charge, just passing Reid stuff with Dem votes shows them as very weak.
The sad fact is that none of the others challenged him as Speaker (by running themselves) and that Speaker vote was just after the tax standoff where Bohner passed that Reid compromise with Dem votes.
I was posting here for a couple of weeks before that to challenge your(their) favorite House member to take a real stand, where was Lou Gomert TX ?? Voting for Mickey Mouse instead of running himself?
