In the upcoming runoff election, the amount of money raised isn't as important as how much they have left.
The figures reflect each candidate's April 24th statement, so we should expect that the candidates spent some of this money before the general election ended. Still, the graph gives a good indicator both of the depth of their fundraising and the potential reserves for their upcoming runoff election.
For instance, although Nevitt raised significantly more funds than Watters, his financial reserves were just $2,400 more. Meanwhile, in District 3, Lopez retained an overwhelming advantage both in total fundraising and reserves.
