Seen Big Foot lately? Then you've probably seen an undocumented worker using a fake ID to vote.

OK, I admit I copied the title from the article, I'm lazy.

Ahem... That aside, this is actually an important issue considering how legal votes for people/things could easily be cast out the window by a fairly large (I'm assuming) amount of illegal votes. At the moment, Republicans are trying to put an end to this (Considering they may feel that their jobs are threatened) however Democrats are equally affected by this (But they don't seem to mind at the moment). Of course this is on the Senate level, so the data may vary. The other important thing here is that the 2/3rds rule for bringing a bill up to debate (At least that is what Kelso is saying, I don't know) was broken. A Simple Majority (18 Senators) brought the bill to debate despite needing 21 Senators (of 31 Senators).

More Research is needed. May edit later.
