Could non-citizens decide the November election?By Jesse Richman and David Earnest October 24 at 3:06 PMCould control of the Senate in 2014 be decided by illegal votes cast by non-citizens? Some argue that incidents of voting by non-citizens are so rare as to be inconsequential, with efforts to block fraud a screen for an agenda to prevent poor and minority voters from exercising the franchise, while others define such incidents as a threat to democracy itself. Both sides depend more heavily on anecdotes than data.In a forthcoming article in the journal Electoral Studies, we bring real data from big social science survey datasets to bear on the question of whether, to what extent, and for whom non-citizens vote in U.S. elections. Most non-citizens do not register, let alone vote. But enough do that their participation can change the outcome of close races.Our data comes from the Cooperative Congressional Election Study (CCES). Its large number of observations (32,800 in 2008 and 55,400 in 2010) provide sufficient samples of the non-immigrant sub-population, with 339 non-citizen respondents in 2008 and 489 in 2010. For the 2008 CCES, we also attempted to match respondents to voter files so that we could verify whether they actually voted.How many non-citizens participate in U.S. elections? More than 14 percent of non-citizens in both the 2008 and 2010 samples indicated that they were registered to vote. Furthermore, some of these non-citizens voted. Our best guess, based upon extrapolations from the portion of the sample with a verified vote, is that 6.4 percent of non-citizens voted in 2008 and 2.2 percent of non-citizens voted in 2010. …Because non-citizens tended to favor Democrats (Obama won more than 80 percent of the votes of non-citizens in the 2008 CCES sample), we find that this participation was large enough to plausibly account for Democratic victories in a few close elections. Non-citizen votes could have given Senate Democrats the pivotal 60th vote needed to overcome filibusters in order to pass health-care reform and other Obama administration priorities in the 111th Congress. Sen. Al Franken (D-Minn.) won election in 2008 with a victory margin of 312 votes. Votes cast by just 0.65 percent of Minnesota non-citizens could account for this margin.
And, of course, many of the non-citizens in Minnesota aren’t lackadaisical Latinos, but hyperclannish and notoriously politically active Somalis. Veteran liberal Democratic state legislator Phyllis Kahn has been on the warpath about Somali vote fraud
against her in primary elections. (Ms. Kahn hasn’t been as exercised about Somali vote fraud in general elections of course.)
It is also possible that non-citizen votes were responsible for Obama’s 2008 victory in North Carolina. Obama won the state by 14,177 votes, so a turnout by 5.1 percent of North Carolina’s adult non-citizens would have provided this victory margin.We also find that one of the favorite policies advocated by conservatives to prevent voter fraud appears strikingly ineffective. Nearly three quarters of the non-citizens who indicated they were asked to provide photo identification at the polls claimed to have subsequently voted.An alternative approach to reducing non-citizen turnout might emphasize public information. Unlike other populations, including naturalized citizens, education is not associated with higher participation among non-citizens. In 2008, non-citizens with less than a college degree were significantly more likely to cast a validated vote, and no non-citizens with a college degree or higher cast a validated vote. This hints at a link between non-citizen voting and lack of awareness about legal barriers.
So, most of the noncitizens who vote tend to be just extreme versions of the base of the Obama Coalition: low-information dwellers on the fringe
of the American body politic.
Now, it could also be that a lot of these uneducated aliens who claim to have voted are just easily confused idiots who don’t remember accurately. For them, of course, we must have a Path to Citizenship!
