(CNN) - Robert Gibbs, a top strategist for President Barack Obama's re-election campaign, on Sunday chided Republican presidential candidate Mitt Romney over his second place finish in the Kansas caucuses.
"I think yesterday was instructive," Gibbs said on CBS' "Face the Nation." "I think it shows you've got some, some real problems on the road to this nomination."

Former Sen. Rick Santorum of Pennsylvania captured the Kansas caucuses on Saturday, beating Romney, Newt Gingrich and Ron Paul.
Gibbs predicted the Republican race will continue for "a matter of months," and said it was unclear if a nominee will be decided before the GOP convention in August.
"I think probably anything is possible," Gibbs said, adding that the longer the campaign goes, the better it likely will be for Obama. "If you look at what these candidates have been saying, tearing each other apart with negative ads, it is a process that in many ways has torn each of them down and I think has weakened them for a fall election."
The Alabama native also offered some advice to Romney, the former Massachusetts governor who has recently taken to saying "y'all" and referencing his love of grits while on the campaign trail in the South.
"As a Southerner, I would tell him that kind of stuff doesn't really go over well in the Deep South," Gibbs said. "I will tell him this. He might not have heard this. But if somebody says they love the SEC, it's not the investigative body that looks into offshore Cayman bank accounts. In fact, it's the world's greatest college football conference."
