Voting twice is a problem. That's one more time than allowed.
The fact that this woman is a Republican really has no more than poetic significance. Vote fraud is rare. Impersonation fraud is exceedingly rare. And when it happens it is virtually never organized. It happens and we have laws to combat it. But one party has wildly exaggerated and demagogued the issue as a cudgel to stop people from legitimately voting. And that's a very big deal.
So, yes, every time a Republican gets nabbed like this it's worth pointing out to combat the Republican fable that voter fraud is something black people, ACORN, Mexicans, illegal aliens and whoever else do to steal elections from good Republicans.
