The entire Republican voting base is ignorant of what goes on. They could hardly be otherwise - they have been immersed in corporate controlled mass media their entire adult lives. I think it is largely the fault of the corporate fascist movement that took over the Republican Party, especially its dominating influence on US media. It's not a matter of "sides" - there is the US fascist movement, and there is everyone else in all their variety. The fascist movement frames the public discussion. I think the root cause of that is the single major factor - a complex "cause" that dates to the Civil War, and lies underneath the capitulation to the corporate media feed and fascist rise. A point passed years ago. 1980, to be precise. They are, on average, according to surveys and polls and such, the most liberal and left-leaning citizens of the country. Whatever "swinging" they do is not between "sides", usually, not between Republicans and Democrats - it's between voting and not voting. The continuing efforts of the Republican Party to discourage them from voting (the Rep marketing pros know what they favor, and would vote for) is a very large and significant factor - it's what the Reps are doing with the Russians, with the various ID requirements and infrastructural manipulations, and so forth. The Reps aren't digging for votes - they are trying to bury them. You share that belief with the nonvoters of the US - the fraction with plurality, in almost all elections. It's part of the "bothsides" lifeboat, built by Republican media pros to allow escape from blame for the consequences of what they have done. There will be such a boat for the agw deniers to flee in, when disaster strikes. What is obviously a Republican Party stance now will be transformed into "bipartisan" error, blamed on everyone alike , just as with the various disasters of W's administration or Obama's Congress.
