Pat Roberts would be strongly favored, but Chuck Schumer doesn’t need to defeat Roberts to win. The DSCC had 4x as much money as the NRSC at the end of June and is only defending a fraction of the seats the GOP is. So all Schumer has to do is drop a million or two into Kansas and suddenly the GOP is spending money it doesn’t have in Kansas instead of New Hampshire, Louisana or Colorado.
That is a possible senario. And perhaps Slattery retains some of his former fundraising savvy.
