It is one of the biggest myths of modern politics: that repetitive advertising (or the spending of campaign money in general) can ensure electoral victory.
Every argument of “campaign finance reformers” is false. There is no (or almost no) correlation between campaign spending and victory. Only a slight number of voters (maybe 1, 2 or 3 percent) are manipulatable by repetitive ad spending.
The vast majority of voters do not change their votes in response to political spending.
Finally, political observers are waking up to this reality. See this fascinating expose here.
Most Americans never donate to political campaigns. They wisely view such spending to be an utter waste. Billionaires who have spent fortunes on politics are increasingly admitting that their contributions have made little difference.
