Here's Bush's current mindset: Don't raise taxes, don't cave on abortion and related social issues, and I'll get re-elected. Everything else I can co-opt to eat into Dem-leaning but currently vulnerable swing groups: Jews (finally waking up to see which party supports Israel), Hispanics (pro-family, pro-life), and Union members (pro-gun, pro-life).
I'd like to add that in spite of what people say here on FR, all three of these groups are very winnable for Bush, and could result in an historic era of dominance for Republicans. But this idea will suit you well or poorly, depending on what kind of conservative you are. If your main issue is abortion, you'll be at least somewhat happy. If it's immigration, you should be at least somewhat pissed off. I think all of us feel a bit of both.
For conservatives to get much more from Bush, we have to give him the Senate in November. He should be doing better NOW, though, in bargaining with the Dems. There's honestly no excuse for it.
But his current haplessness could also be by design: Always smile, say almost nothing bitter or partisan, and you suddenly contrast heavily with Daschle, who kicks and screams like a baby to get his way and, to some extent, gets it. The discontent against the party in power somehow transfers to Daschle, and the election goes our way. At least, that's the thinking.
