WASHINGTON _ Sen. Pat Roberts of Kansas looks vulnerable to Democrats _ and some Republicans, and that's a big reason the 2020 race has quickly drawn a prominent potential challenger, former U.S. Attorney for Kansas Barry Grissom.
Grissom confirmed Monday that he's been considering a run for U.S. Senate as a Democrat for roughly a year.
He's not officially made his decision, but he's actively is laying the groundwork to mount a challenge against Roberts, the Kansas Republican who has been in Congress for nearly four decades.
