I think Arnold will be tied up with California's problems for a while. If he does hit the road for Republicans, Arnold won't be campaigning on the issues of pro-life, pro-2nd amendment or in opposition to special rights for homosexuals and against amnesty for illegals. And the jury is still out on whether Arnold supports income tax cuts, associated with supply side economics, reductions in actual spending, associated with efforts to cut waste, fraud and abuse, and cutting back on social welfare entitlements to illegal aliens and societal deadbeats.
We shall see.
