According to NPR, because Alaska is a cheap media market, with a vulnerable incumbent Democratic senator, we have been inundated with Koch brother (and other's) money to sway the election. TV programming, the mail, our front porches and telephones have all become unusable extensions of the campaign with the result that Alaskans are enraged. At everyone.
It's not just the negativity that grates, it's the cognitive effort to have to keep listening to the Republican ads, and then mentally debunking them.
For example, the ads try to tie Begich to Obama's "failed" policies without naming them. Are they the ones that brought unemployement below six percent? Are they the ones that (using the Republican blueprint, credit where credit is due) got health insurance to millions of uninsured people? The record stock market? Killing bin Laden?
They certainly don't want to talk about their own record. While they bemoan the national debt, they shut down the government rather than even discuss raising the taxes on billionaires that pay at lower rates than the middle class. They don't want to discuss the policy that led to the invasion of Iraq, at a cost of over a trillion dollars, a war that was so mishandled that it created ISIS. Although they do seem eager to get back into that war. Do they want to talk about their voter suppression or their views on legitimate rape?
I only mention this as confirmation of the NPR report, we are enraged. Unfortunately, as a red state, most of us are enraged at the wrong people.
