Obama is tops in Virginia primary. Haven't heard the exact percentage yet. Virginia is an open primary, and theory I'm hearing is: since it's obvious McCain has the Republican nomination---(despite Huckabee's dragging it out)--- many Republicans--especially moderates to liberals--(and of course independents) are voting in the Democratic primary. Obama is lopsidedly getting the benefit.
I've also heard on the call-in radio show (CNN?) several voters say they voted for Ron Paul--but will vote Obama in the fall. Iraq war stance was cited, as was ability to unite the US.
Maryland primary closing time has been extended to 9:30 (from 8), due to traffic problems influenced by the "wintry mix" we are enjoying.
