Who says they actually are?

If you were the White Hats, you have several objectives.

1. If it was apparent that Trump is really running away with the election and it's a landslide, then Democrats would know that massive cheating isn't going to change the results. The massive election fraud would halt and the cheaters would stay in the shadows. Cheating works when an election is close, within 1% to 3% or so. If you want to catch people cheating, vote fraud, bribery, illegal funding, fake ballots, etc... then you convince everyone that the election is very close and Kamala can win. By election day, when they realize Trump won easily, it's too late. They all just massively cheated and many will be caught.

2. If it was apparent that Trump is winning in a landslide and Kamala has zero chance... the Deep State (uniparty) would spare no effort to disrupt the election. They would step up to next level, including another 9-11 event. Anything they can do to disrupt the election would be done. Desperate people do desperate things. As long as they believe Kamala has a chance and is within a 1% or 2% margin of beating Trump, then the election continues and they wont disrupt it. After all, they might win by cheating again. White Hats are smart to keep them thinking that Kamala has a chance.

3. If White Hats want to ensure that the election cheaters, those funding them, those giving the cheaters legal protection, etc... remain in place waiting for election results, rather than going into hiding or hiding assets... then make it look like Kamala has a good chance to win, and that the cheating may put her in the White House. Nobody will run or hide assets until its known that Trump really won in a landslide. By then, all the bozos can be rounded up, bank accounts frozen, yachts seized, names added to no-fly list, etc... .

There are good reasons why White Hats want to keep people thinking it's a close election.
