Well if someone deviates from 'conservatism' then how are they 'ultraconservative'? That is assuming some sort of coherent definition. You're still not making any sense. If you had said 'neo-conservative' or 'christian conservative' then I would agree with your point, but you didn't.
I think I said these people had no credibility as fiscal conservatives, not that they were fiscal liberals. It's not like these people actually support fiscally liberal policies; they just oppose spending cuts to their myriad pet projects, which in practical terms comes out to be largely equivalent to fiscal liberalism.
Which.. is not fiscally conservative and hence fiscally liberal, because they support more government spending. Again, doesn't make sense. This is like if someone posted that some church was very fundamentalist, but had no credibility because they believed in evolution and were universalist. It's incoherent.
