Along with every other Republican, Frank LoBiondo voted against increasing the national debt ceiling and "pay-as-you-go" rules today. Of course, you're not foolish enough to think that his vote against debt means anythihg. Back when Republicans controlled the House and the Presidency, they were the ones who voted for debt ceiling increases and Democrats voted against them. For example, here's LoBiondo's 2004 vote to increase the debt ceiling. So now it's the other way around, but it doesn't mean anything sincere.
The second vote may be a little more sincere. Republicans like to give tax cuts without cutting spending, which would be illegal under the "pay-as-you-go" rules. Of course, it's the opposite of being a "fiscal conservative."
