As far as the change I would like to see. I think all state level and federal level elected officials should be elected to 6 year terms, with 1/6th being replaced each year. There would be no need for a congressional pension (where else can you work 6 years and get a pension) and only those that were truly willing to serve would be willing to run. After being elected you could never run for that office again. Once a Senator you could run for President or US Rep but never for Senate again. Same ting would be used for state offices.

FYI- the 3/5ths rule was put in place by the politicians of the northern states. The southern states wanted to count each person as a whole person but the abolitionist from the north only wanted to count slaves at a 1/2 rate, thus the 3/5th compromise. Read more on wikipedia

 

As for giving less populous states too much power, it does not? States get electors based on population, so a state with twice Kentucky's population would have twice as many electors. The difference is the larger states tend to support liberal / democratic candidates while the smaller states tend to support conservative / republican candidates, while this is not an absolute a look at the electoral map from any of the last several presidential elections will show this to be true.

You are completely incorrect about the EC. It does over-represent smaller states. In fact, it was created as a compromise for small states to ratify.

 

Take a state that has only 3 Electoral College votes, the fewest possible (2 Senators and a House Rep.) A state might have double the population but only 4 Electoral College votes (2 Senators and 2 House Reps.) No matter how we string this out, we never reach the correct proportion, ie, a state 50 times as large gets 52 EC votes which is about a hundred short of being 50 times the smallest possible representation.
