I just played a bit of a game. Was playing on Normal, doing great, had every state but Hawaii and Maine under my belt by week 10 as the Democrats, but then I just started losing states around week 30, I had no money, and I couldn't get around to get them back. May be my strategy, but a TV ad brought the whole country under my belt early on.
Also, I noted define lags, mostly clicking on state details, and switching between endorsements, and generally after clicking anywhere in the game on something outside of the map caused a drag about 1 out of 3 times. Only happened a few times on the map.
