Look into how Loretta Sanchez won a congressional seat in 1996, narrowly defeating the incumbent Bob Dornan.
Her campaign explicitly courted the votes of illegals, encouraged them to vote illegally.
She defeated Dornan by fewer than a thousand votes. Subsequent investigation proved that there were at least seven hundred illegal votes, and likely thousands.
Not only did illegals vote in that election, but it is almost certain that their votes changed the outcome.
Since 1996, has our electoral system become more secure, or less?
