If any person shall give, or offer to give, directly or indirectly, any bribe, present or reward, or any promise, or any security, for the payment or delivery of money, or any other thing, to induce any voter to refrain from casting his vote, or to prevent him in any way from voting, or to procure a vote for any candidate or person proposed, or voted for as the elector of President, and Vice President of the United States, or Representative in Congress or for any office of profit or trust, created by the Constitution or Laws of this State, or by the Ordinances, or Authority of the Mayor and City Council of Baltimore, the person giving, or offering to give and the person receiving the same, and any person who gives or causes to be given, an illegal vote, knowing it to be such, at any election to be hereafter held in this State, shall, on conviction in a Court of Law, in addition to the penalties now or hereafter to be imposed by law, be forever disqualified to hold any office of profit or trust, or to vote at any election thereafter. But the General Assembly may in its discretion remove the above penalty and all other penalties upon the vote seller so as to place the penalties for the purchase of votes on the vote buyer alone.
