I've consistently noticed, in every poll where the question's been asked, upwards of 70% of voters, and usually above 80% of voters, support tough border enforcement. IMO, the candidate that comes out strong on the border has the best chance to win in '08, regardless of party. It's the one issue most rank and file members of both parties agree on, and could rally around, especially if the Dem candidate is generally unpalatable (Hillary.)
If Duncan Hunter is steadfast and articulate on that one issue alone, he could win, and win handily, because you know the Dem challenger, whoever it is, will be all over the board on that issue.
If the Pubbies run on border security, '08's in the bag for them.
That 70 to 80% will collapse as soon as the MSM begins its campaigns against border control.
They haven't started yet because they would be agreeing with the President.
But any Republican that runs on illegal immigration will be destroyed.
It doesn't mean a Republican shouldn't try, but the MSM and Hollywood always, always, always, win in the end.
