Sure, let's go ahead and allow 14 year olds to vote. Since that would also give them the ability to vote on many issues involving the law/legality of things such as abortion, same sex marriage, etc., on a state and national level, when they happen to commit a crime they will in turn be treated at the adult level. No more expunging of juvenile crimes when they reach 18 or 21. If they are male, they should also be required to follow the military drafting law that all male U.S. citizens, and male aliens living in the U.S., who are ages 18 through 25, must register with the Selective Service System. We will simply change the threshold to 14- 25 years of age. While we are at it, it's a no brainer to also give them a drivers license even though it is fact that 14 year olds brains do NOT have the capacity to react or think ahead more than ~3 minutes as far as consequences for actions. *No, please don't insert the argument as to 'old people' and their reaction time while driving. It has zero to do with this right now.
This list could go on and on, but if you are reading this and able to comprehend what I have said, you will get the point.
There are certainly 14 year olds out there with more knowledge and capacity to research/ understand how the voting process works vs many in their 30's. I am NOT saying that age is always a restriction when it comes down to certain things. Personally, I don't want to walk into the voting booth and see Justin Bieber's name under write in candidates......
