Wow, I'm shocked to see this from Philip considering his normal philosophy, though I am in agreement with him.
1. Usually, the EC winner is the same as the PV winner. It is highly unlikely to have two different winners.
2. It makes candidates visit swing states, rather than just run up massive totals in big states, and ignore places like Nevada, New Mexico, and New Hampshire.
1. So? 2000 shows when that's not the case it's hardly a non-factor.
2. So instead the safe states get ignored. The conservative parts of upstate New York becomes moot, as does the Deep South's black population and the numerous conservative parts of California. It doesn't result in every state being visited, rather only a handful.
