Here’s why the thermometer matters — and matters for Warren in particular. It’s a measure of passion, which is, of course, the sine qua non of politics. While passion isn’t everything — fundraising matters, organization matters — it’s hard to get elected to anything without passionate supporters.
And, Warren quite clearly evokes that passion. Need examples beyond the poll? Warren collected more than $42 million for her 2012 Senate campaign, a massive sum that is indicative of the passion — and national following — that Warren evokes. Then there is the speech she gave at the 2012 Democratic National Convention, which, if you forgot, was among the best received addresses of the gathering.
