If the Republicans have any sense, they'll find a strong female candidate and have her run against Hillary...if there is such a thing in the GOP.
My predictions for 2008, as they stand now:
The neo-cons will probably take the fall in `08, like the Dems took the fall in the last two presidential elections. The game is fixed, and no one wants to stay in power for too long. They've accumulated their power points, and when they leave their executive public offices they will finally be able to relax, call in a few favors, make some real money, and plan for 2012, 2016, or 2020. Their goals were to start a quagmire in the middle east and establish a state of fear domestically so that no police state measure can be rejected. They've made as much initiative with it as they can in this cycle - though some things are yet to play themselves out, the ball is already in the air. The next president will be a centrist, a weak Republican or a free trade Democrat, and either way his/her goals will be to increase the socialist programs closer to the European standards, to strengthen and expand NAFTA, and to continue being strong on "national security".
Condoleezza is too closely associated with this administration and, sadly, a smart black woman still can't win in places like Mississippi - they'd want to save her for the next election they really want to win. McCain was too old eight years ago, and he's never really been a part of the inner circle. If either of them two run, they're set up to loose. The "Arnold Amendment" process would have needed to be a lot further along by now, so it won't happen for `08. Amongst the current Republicans, only
Giuliani is centrist and elite enough for the aforementioned needs: if he runs, he'll win.
Among the Democrats, I would place
Richardson as the most likely nominee, yes, beating out Hillary. Evan Bayh and Tom Vilsack are strong Dem candidates as well.
Among the third parties, I predict very bad news for Libertarians on national level. The Constitution Party, strengthened by a centrist Rep candidate and border security, will surprise everyone and grab as much as 5% of the popular vote. The Green Party, strengthened by a centrist Dem candidate and no longer suffering from a Nader/Cobb split, will take 4th place. LP, the
Party of Principle, will find itself 5th.
Only political migration and secession present a genuine, substantive hope for "liberty in our lifetime". Everything else, even including the LP on the national level, is a distraction.
