That does not measure depth of support, only intensity of supporters. You know who else had massive rallies right up to election day? George McGovern. That didn't work out so well for him did it. Nader could fill arena's during his presidential runs, but that didn't amount to squat. Heck Ron Paul could get huge crowds near college campuses, but again, that just shows what followers he has are intense about him.
With that and as long as electronic programmable vote and vote counting machines are the predominant means of casting and tallying votes and the allowed stuffing of absentee ballots, it will be hard to convince me and whole lot of other people that the 2012 election was not stolen.
The same thing the Democrats said when they lost the off year elections in 2002 and the presidential election in 2004. Kerry had huge crowds, and the intensity of an opposition and media that hated Bush with a passion - he still lost. The left blamed Diebold and other nefarious plots with voting machines. They didn't really let go of their "black box voting" conspiracies till they started winning again in 2006.
We are simply following along the same path Europe is. They are voting secular socialist, and we are doing the same. I understand it is hard to accept that the American public is so far gone, but think about how dramatically the demographics have changed. Look at California. California is in the gutter yet just voted for a Democratic legislative super majority. It ain't vote fraud man, its a public that is growing increasingly ethnic, ignorant and dependent. Sorry, but that's the reality. We're just not the same country we once were.
