Ron Paul's strength in both the Vermont and Virginia Republican primaries came largely from Independent voters and, to a lesser extent in Vermont, Democratic voters who chose to participate in their state's Republican primary. Although Mitt Romney won both states handily, Paul won a significant portion of the vote.
Almost a third of the independent voters in Virginia voted for Ron Paul. In contrast to this, over 70 percent of Republicans voted for Mitt Romney. Half of Paul's votes came from independents and another 7 percent came from Democrats.
In Vermont, 38 percent of independents voted for Paul as did 42 percent of Democrats. Almost 60 percent of Ron Paul's voters were independents and another 15 percent were Democrats. Only 13 percent of Republican voters in Vermont voted for Paul. Romney won half of the Republican voters in the Vermont primary.
