Being a constitutional republic does not mean we should not and cannot guarantee the election of the presidential candidate with the most popular votes. The candidate with the most votes wins in every other election in the country.

Guaranteeing the election of the presidential candidate with the most popular votes and the majority of Electoral College votes (as the National Popular Vote bill would) would not make us a pure democracy. 

Support for a national popular vote has been strong in every smallest state surveyed in polls among Republicans, Democrats, and Independent voters, as well as every demographic group
		
Among the 13 lowest population states, the National Popular Vote bill has passed in 9 state legislative chambers, and been enacted by 4 jurisdictions.
