Could you be offered enough money to vote for the candidate you despise most?
My one vote means nothing in the election.
If you could be bought, you don't deserve to vote in my opinion. You don't value that right highly enough.
Absolutely not. No matter how much money. (And I say that for a lot of things; not just my vote.)
Yes, my vote could be bought. It would cost enough to live independently with more than enough left over to to buy the candidate in question twice over.
Maybe for $1million, but no one in their right mind would give that kind of money away for 1 vote.
