Notable Quote of the Day

“Put another way, if you’re wondering why candidates such as Castro and Booker aren’t gaining more traction despite seemingly having run competent campaigns, the answer may have less to do with them and more to do with the fact that the field has a lot of heavyweights. Biden is a former two-term vice president; Sanders was the runner-up last time and basically built an entire political movement, and Warren and Harris have been regarded as potential frontrunners since virtually the moment that Donald Trump won the White House. The years that produce volatile, topsy-turvy nomination races, such as the 1992 Democratic primary, tend to be those where a lot of top candidates sit out, perhaps because they’re fearful of running against an incumbent with high approval ratings.”
