Which of the alternatives to the electoral college system do you think is the most democratic?

The National Popular Vote bill is the realistic alternative for how we elect the President.  It is 61% of the way to going into effect.

By state laws, without changing anything in the Constitution, The National Popular Vote bill would guarantee the majority of Electoral College votes, and thus the presidency, to the candidate who receives the most popular votes in the country, by replacing state winner-take-all laws for awarding electoral votes in the enacting states.             
                                                                                                                               Every vote, everywhere, would be politically relevant and equal in presidential elections. No more distorting and divisive red and blue state maps of pre-determined outcomes. There would no longer be a handful of 'battleground' states where voters and policies are more important than those of the voters in 80% of the states that now are just 'spectators' and ignored after the conventions.
                                                                                                                               The National Popular Vote bill would take effect when enacted by states possessing a majority of the electoral votes—270 of 538.
All of the presidential electors from the enacting states will be supporters of the presidential candidate receiving the most popular votes in all 50 states (and DC)—thereby guaranteeing that candidate with an Electoral College majority.
                                                                                                               
The bill uses the power given to each state by the Founders in the Constitution to change how they award their electoral votes for President. States can, and have, changed their method of awarding electoral votes over the years. Historically, major changes in the method of electing the President, including ending the requirement that only men who owned substantial property could vote and 48 current state-by-state winner-take-all laws, have come about by state legislative action.
                                                                                                                               In Gallup polls since 1944, only about 20% of the public has supported the current system of awarding all of a state's electoral votes to the presidential candidate who receives the most votes in each separate state (with about 70% opposed and about 10% undecided).
 
Support for a national popular vote is strong among Republicans, Democrats, and Independent voters, as well as every demographic group in every state surveyed recently.  In the 41 red, blue, and purple states surveyed, overall support has been in the 67-81% range -  in rural states, in small states, in Southern and border states, in big states, and in other states polled.
Americans believe that the candidate who receives the most votes should win.       
                                                                                                                               The bill has passed 33 state legislative chambers in 22 rural, small, medium, large, red, blue, and purple states with 250 electoral votes. The bill has been enacted by 11 jurisdictions with 165 electoral votes – 61% of the 270 necessary to go into effect.
