Well, there's a lot I'm unhappy about with President Bush and the Republican Congress, but we've accomplished much more than you say. (Taliban out of power; Saddam out of power; military reorganized and built up; Roberts and Alito on the Supreme Court; other conservative judicial appointments; some slight progress on education, social security, and immigration; etc.) It is important to keep pushing for more, and to push back hard when mistakes are made (e.g. Harriet Miers), but we conservatives are supposed to be optimistic and believe in the people and the power of the truth. Our best days are still ahead. Ronaldus Magnus said it. I believe it. Etc.
I might be less than satisfied with many of Bush's positions on things such as immigration and 'social' spending, but I'm unwilling to sacrifice our American civilization as those on the Left are all to willing to do.
We're not gong to have a future unless and until we do a little house cleaning within our own borders. That won't be pretty, but it will be necessary.
As I have said before, those who seek the destruciton of a free society - no matter who they are - are unfit to live in that same society. It's not just a matter of a difference of opinion that we're talking about here.
