Why? The electorate votes for the what they want. If that's the same guy, year after year... you'd be saying that the electorate shouldn't have the right to vote their choice.
A better choice would be to require that anyone who wishes to vote have to pass a civics test, so that only those who understand how the government works can vote. Thus eliminating any @sshat that thinks the President is some magic-man that can pull free stuff out of a hat.
Why you ask? You really think this is working? Both candidates in 2008 tried to out Santa each other. Incumbent congressman have a huge advantage at getting re-elected and at bringing back the $$$. Congress hasnt polled over 40% in decades.
I agree with you 100% on civics test, everyone should have to know how Washington passes laws. I have believed that for a while. But two problems , 1) the history of election tests in South will label it white racism, 2) those in power will write the test to get opposing voters excluded.,just like McCain's campaign finance laws.
Term limits are a key step. They should have to put their kids in public schools while in congress, and white house. I know those will never happen,
