Liberals can rationalize anything.
ditto. do they actually have human brains or are their brains missing or deformed?
I do sometimes wonder about that.
When it's in their interest to do so. In this case, they are running out of voters. Their lunatic policies are being rejected by everyone except Blacks, the free stuff crowd and outright Communists. That's not enough to win elections, so they have encouraged widespread illegal immigration who will provide a reliable voting block. Voter fraud hasn't provided enough votes either, so they must permit non citizens to vote.
It's all about votes.
Liberals believe that we are all citizens of the world. They do not recognize national borders. They have no loyalty to individual nations. Therefore, voting in whichever particular location you happen to be in at the time makes perfect sense
If it means more Dimocrat votes...
