Approaching 60% in MD, NY, CA, IL, VT, CT and Iowa? He could very well lose the EC and win the PV if this pattern continues.
The problem is, McCain has his own share of "close to 60" states. The latest poll from TX is McCain 57%, GA - 57%, TN - 59%, KY - 57%, AZ - 56%, SC - 58%, AL - 60%, OK - 59%, NE - 60%, UT - 65%, WY - 66%, ID - 62%. So, if anything, it could go eiter way 
But places like Wyoming and Idaho have next to no population, while NY, CA and IL are among the biggest in the nation. Furthermore, if you compare to "traditional" results Obama seems to have gained disproportionately among safe states on either side. But I still expect the popular vote and electoral vote to match each other more or less. If they split, I think Obama is more likely to win the PV and lose the EV though.
