Well they only publish trades ~30 days later. There's no real chance of front-running a politician and for all you know they could've closed their position before the 30 day period ended. Plus, if people follow them into the trade (i.e. people buy because Pelosi bought) that only moves the price in the politician's favor. It's not like politicians are running crazy strategies that you can figure out from their trades, so I can't really imagine it creating any incentive to hide trades
