It makes sense.
Cut the middleman out of the equation, and this country could save literally billions of dollars each election cycle and have a more efficient government to boot. Think about all the money that is spent on political campaigns... and hell, half of it goes to losing candidates in the first place. You might as well flush those millions in donations to Kerry, McCain, Hillary Clinton, Romney or Ron Paul down the toilet for all the good it does.
If corporations and the rich can just vote directly, you can stop the whole song and dance around campaigning and just cut right to the issues. You'd also cut emissions from all the constant travel politicians are doing glad-handing every police chief across the country.
Plus, if you cut down the time politicians spend worrying about getting elected, you'd be leaving them a lot more time to actually do some governing for a change.
With all the extra money saved, the job creators can then create even more jobs, meaning the wealth will trickle down to the rest of the economy instead of getting sucked into the black hole that is politics. It also means that people can literally vote with their wallet by not patronizing corporations that vote against their interests.
The rich already pay so much in taxes to this country that it makes sense that they should get more of a say -- it's only fair. When you make family decisions, do you let your kids have an equal say in what happens? Of course you don't. It's the exact same thing here.
I think we could stand to have a more efficient political process and this seems like just the ticket. What could go wrong?
