In a small town, there are two candidates contesting an election. If 19% of the total voters do not cast their vote, and 1,500 votes are invalid, the winning candidate secures 48% of the total votes and wins by a margin of 3,000 votes. If another city, Newtown, has three times the number of voters as the small town, and in Newtown’s election, 3,500 votes are invalid, and the winning candidate receives 55% of the valid votes, what is the difference between the valid votes obtained by the winning and losing candidates in Newtown?
