Could non-citizens decide the November election?

Could 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.
