In an article in Politico, Mark Rozell, acting dean of the School of Policy, Government, and International Affairs at George Mason University, and Paul Goldman, a weekly columnist for the Washington Post, point out a fact that should greatly concern all Americans: that the presence of millions of noncitizens, both legal and illegal, could tilt the presidential election toward the Democrat Party and decide the election in favor of the eventual Democratic nominee. 
Voter Fraud Happens
As I have outlined in many different articles and a recent book on voter fraud, illegal voting by noncitizens is a growing problem. Most election officials are not taking the steps necessary to detect or stop it, and many prosecutors including the current Justice Department seem reluctant to prosecute it. 
A study released in 2014 by three professors at Old Dominion and George Mason Universities in Virginia concluded that 6.4 percent of the noncitizen population voted illegally in the 2008 election, enough to have changed the outcome of various contests in a number of states.
That includes the winner of North Carolina’s electoral votes, which went to Barack Obama by a relatively small margin, since a majority of foreign-born residents favor the Democratic Party.
That may also be why Virginia Gov. Terry McAuliffe, the governor of a battleground state, vetoed a bill that would have required jury commissioners to provide local election officials with the names of individuals called for jury duty from the state’s voter registration list who were excused for not being U.S. citizens. 
 Some States Have Congressional Districts They Shouldn’t Have
 But as Rozel and Goldman accurately point out, noncitizens may be changing the outcome of presidential elections even without voting illegally. This is related to the problem of some states having more representatives in Congress than they should, and others being shortchanged unfairly due to the huge–and growing–population of illegal aliens whom the Obama administration and its political allies want to provide permanent amnesty.
All of this stems from the way apportionment is conducted.
 There are 435 members of the U.S. House of Representatives. Under Sec. 2 of Article I of the Constitution and Sec. 2 of the Fourteenth Amendment, every ten years, after the “Enumeration” (the Census), we redistribute those 435 seats based on the “whole number of persons in each State.” In other words, the number of members of the House that each state gets is based on the total population of each state relative to the total population of the U.S., which includes noncitizens. Thus, the upwards of 12 million illegal aliens present in the U.S., combined with other aliens who are here legally but are not citizens and have no right to vote, distort representation in the House.
