Proposal: all taxpayers should be automatically registered to vote

Here's a simple proposal:

Let's pass a law that automatically registers every taxpayer (and dependent) to vote.

Why?

Because the current voter registration system is insane - and because it would be so easy to do.

All taxpayer records are computerized. They are kept exceptionally clean, so there are very few duplicates or errors.

What is the possible downside?

If someone doesn't want to vote, they don't have to.

If someone isn't a taxpayer or dependent, they can register under the current system.

If someone is a taxpayer but not a citizen, a flag would have to be set somehow in the file so the person would not be eligible to vote.

Politically, it's a win-win.

Republicans would love this system because fraud would be practically non-existent.

Democrats would love this system because every eligible citizen would be automatically registered to vote, saving hundreds of millions in voter registration drives and voter protection campaigns.

Election officials would love this system because they would not have to maintain a massive database filled with errors large and small that cause nightmares before, during, and after Election Day.

All in favor?
