One whole year more

How much longer are we going to put up with two years of people running for President?
Polls, and polls, and polls, and polls, almost always wrong!
Maybe a billion dollars spent by lobbyists!
QWe need a Constitutional change where each state nominates one person for President, then those 50 people decide in conclave who will run. To be accomplished in 60 days!
Fifty for each party or if some state wants an independent, Ok, send them.
No one can be nominated who has served over four years before and there are no status qualifications.
