People do not vote for parties - at least technically - they vote for people.

>>> that swing voters hold a disproportionate amount of power

How is it a bad thing? You say people that actually look at the issues at hand and not just mindlessly pull the lever for "our guy" whoever he is hold "disproportionate amount of power". I say they should hold 100% of the power - or 100% of the voters should be like this. The fact that they aren't is exactly the problem!

>>> given that the swing voters are usually not as politically interested as bloc supporters.

"Politically interested" can mean different thing. If bloc voters' only interest is getting "their guy" in power, and keep him there whatever happens, I don't have any sympathy for such kind of political interest. And if you want to see how well it works for those bloc voters, see how well it worked for voters in Detroit or Chicago, who are constantly voting in crooks and mob men.
