Voting is destroying this country.
Absolute universal voting was never an intent of our founders.
26 year old white land owning males is a bit too restrictive.
I would eliminate the presidential election all together. Congress, through the HoR should appoint the president, to be ratified by the Senate. Senatorial elections should also be eliminated, the state governments should once again appoint them.
This would do a lot of good. Firstly, it would remove a lot money from politics. Secondly, it would likely remove a lot of the polarization we have today, perhaps the executive and legislative branches could work together. It would also weaken the parties, at least the two biggest, probably allowing for smaller third parties to emerge.
America was a unique experience at the time of it's founding. However, now this form of government has been perfected a bit. Most democratic republics appoint their executive.
Voting should be restricted to 18 year olds who file a tax return. This return would be used as the voter ID. It would only be valid for voting if the person was not on Government assistance.
