When we last checked in on Dave Wasserman's popular vote tally (based on county-by-county tabulations), Mitt Romney was at 47.58 percent of the vote. His total has been steadily decreasing as the vote continues to be reported in heavily Democratic states like California, and as heavily Democratic provisional ballots get tallied everywhere.
As we noted yesterday, President Barack Obama already has a higher popular vote margin than George W. Bush had in 2004. While Bush's margin over John Kerry was a sliver over 3 million, the margin in 2012 now exceeds 4 million votes.

Obama has also officially exceeded Bush's margin of the vote—50.73 in 2004, versus 50.75 percent today.

Poetic justice: Romney likely to finish at 47 percent
