Here are the current popular vote totals assuming several different scenarios, including with or without Fl and/or MI. Also they give an estimate as to what these totals would be with IA, NV, ME, WA which have not yet released popular vote totals (I'm not sure when they will be released, so maybe someone who knows can answer that)

NOTES from realclearpolitc
"*(Iowa, Nevada, Washington & Maine Have Not Released Popular Vote Totals. RealClearPolitics has estimated the popular vote totals for Senator Obama and Clinton in these four states. RCP uses the WA Caucus results from February 9 in this estimate because the Caucuses on February 9 were the “official” contest recognized by the DNC to determine delegates to the Democratic convention. The estimate from these four Caucus states where there are not official popular vote numbers increases Senator Obama’s popular vote margin by 110,224. This number would be about 50,000 less if the Washington primary results from February 19th were used instead of the Washington Caucus results.)
**(Senator Obama was not on the Michigan Ballot and thus received zero votes. Uncommitted was on the ballot and received 238,168 votes as compared to 328,309 for Senator Clinton.)"
