The DSCC has for months now insisted that the Connecticut Senate contest is firmly within the Democratic column. And for a time the polling validated that rhetoric. The problem for the committee, now, is that both polling and their spending betrays that notion. After reserving roughly $500,000 in television advertising a couple days ago, the DSCC added yesterday $1.2 million to its ad buy for the remaining three weeks, according to the Washington Post’s Aaron Blake.
