Sorry, but it still reads the same to me. If the GOP is to the right of the centerline, and Arnold advocates crossing over the centerline, then it stands to reason he advocates a move left.
I don't think it lost anything in the translation.
He said he likes the Republican Party right where it is.
The crossover he refers to is in accepting another 5% into the Party. Cross over the centerline while running for office not while making laws. There is a huge difference.
Unfortunately most Republicans fail to realize the way our schools teach our children to think. They teach they that Republicans act further right than they preach (we don't). They say the same about the Left but the left preaches far, far, far to the right of where they act.
