You want to know why Speaker Boehner has decided to engage in a second attempt to sue President Obama - this time over his executive action on immigration?
It's simple: he's trying to call off the lunatic wing of his party in order to get a funding bill for the Department of Homeland Security passed by February 27th. In other words, now that they're in control of Congress - the whole hostage-taking thing is backfiring on them. They can't afford to bypass the deadline they themselves initiated and allow a shutdown of the Department that is tasked with protecting us against all those scary terrorists who are out to get us. < snark off > It's also why Boehner is going to allow yet another vote on repealing Obamacare.
I'm thinking there is a betting pool available here to be exploited. How long do Boehner/McConnell drag this all out before they recognize that they have to go to Pelosi/Reid to bargain for votes from Democrats in order to keep DHS open? That's the only way they've been able to pass legislation in the past and it looks like that hasn't changed in this new Congress.
UPDATE: During the Loretta Lynch confirmation hearings it has been noted that the current federal budget allows for the deportation of approximately 400,000 undocumented people currently in the country. Sen. Lindsay Graham asked Lynch to determine how much money would be necessary to deport all 10-12 million. We could suggest that he take the amount currently allocated and multiply it by 30. If Republicans want to "deport-em-all," that's how much they need to increase the budget for DHS. Think they can actually sell that?
