For all we know, there could be other coins which have a sizeable lead due to a recent DOT vote, but that lead is not yet showing on the voting page...
Voting results coins are updated once a day or so. It's like a private auction - do not know the amount until the end of the reception rate (((This is not an honest trick! BlokcExplorer Exchange does not show how to address the coins, and the other I have not found.
I did notice that the Cryptopia block explorer doesn't let you search by address, but I may be able to help there.

One of my block inspection utils is able to print out basic out address and amount information for transactions in each block, and with a bit of magical *nix text processing I've come up with 541 transactions of >100 DOT over the past 24 hours. Matching those up with the leaders on the voting page...

....I haven't checked them all, but based on the top coins, only ECC and GRW have had any DOT voting activity today.
I also did a quick check of addresses which have multiple transactions linked to them today - the only one that matches any addresses on the voting page is GRW.
So it looks like we're genuinely ahead. Cross fingers.
PS: I'll set a task on my phone to check again when it's closer to the deadline.
