The House Republican majority failed to pass the Patriot Act, set to expire at the end of February. The Patriot Act is the Act that denudes Americans of their privacy, enables the Government to tap into their phone, e mail, library books, etc. 26 Republicans voted against the bill, while 67 Democrats voted with the Republicans for the bill.
This shows that House delegates do not necessarily vote on party line. The Republican controlled House cannot just assume that they can pass their agenda, despite Obama holding out carrots to them with the tax bill and other recent things.
Or maybe the house members are realizing how it feels to have your privacy eroded, with the Wiki leaks.
