According to what the article appears to say, though, Arnold never had mentioned any intentions of raising taxes. It appears that it's just an accusation on the part of Cruz, not an actual announcement from Arnold himself.
But it's true that he needs to start addressing where he stands on the issues because if he continues to have a low profile, the other candidates can easily get away with false accusations ans sway the public opinion. No doubt Arnol'd popularity will suffer tremendously if Cruz makes an accusation that Arnold wants to raise taxes, and Arnold does nothing to counter that accusation. All that does is lead the public onto a (probably false) belief that they'll be no better off with Arnold in office than davis, from a tax standpoint.
Arnold needs to defend himself. The public might be getting the wrong idea.
But here's what I think might explain his reluctance thus far to address the issues:
A candidate has to plan what they say to the public very, very carefully, because there's alot of groups out there with their own interest and any one of them, if they don't like your policies, can do great things to make sure you don't get into office.
I think Arnold is still in the "planning and avising" stage with his advisors, figuring out exactly what his platform is going to be, before launching the full-scale campaign.
If we wait a week or so, maybe we'll se him come out with a solid platform and begin addressing the issues. Hopefully by then it'll be enough to restore confidence in him. His silence has to be happening for a reason as he genuinely seems interested in helping California recover. That's why I'd put my money on the delay being simply because he's still building a solid platform for his campaign. give it time.
