Yawn. Given that the Chamber of Commerce supports amnesty for illegal aliens in general, not just for the small number of “Dreamers” that Obama half-legalized in DACA (but didn’t place on a path to citizenship) about a year ago, the fact that McSally voted for defunding Obama’s November executive-order amnesty that half-legalizes millions of additional illegal aliens is a huge slap in the face of the Chamber of Commerce. Your predictions that McSally would be a CoC lackey that would support amnesty have been proven wrong, at least so far.
Regarding the Blackburn amendment, House Republicans separated it from the general bill because they knew that *defunding DACA would never withstand a filibuster in the Senate*, and thus trying to defund DACA would sink the entire bill unless it was separated. As we speak, Harry Reid is scheming to have the Senate vote on the Homeland Security funding with the Blackburn amendment attached to it in an attempt to have the Senate filibuster the whole kit and caboodle, while Senate Republicans need to hold firm and have two separate votes, one for the general bill and one for the Blackburn amendment. So, disappointing as it was for McSally and 25 other Republicans to have voted against the Blackburn amendment, it will have zero effect on anything, other than in protecting her from 2016 attack ads featuring nuclear engineers brought to America illegally at the age of 2. The big vote was on the general funding bill, Roll Call 35, in which McSally joined Jim Jordan, Louie Gohmert, Steve King and just about every other conservative Republican (plus the only two Democrats that represent a district in which Romney got 53% or more of the vote) in prohibiting the use of funds for the enforcement of Obama’s massive November 2014 executive-order amnesty. http://clerk.house.gov/evs/2015/roll035.xml
