Rubio sees their strengths:

Their convictions are sincere, the product of each man’s upbringing and early life experience. Mr. Obama’s formative years spent as a community organizer inspired him to consider the poor or unemployed as abused by businesses that shuttered plants or raised rents – victims of an indifferent society. His decision to “organize black folks” as he explains in “Dreams from My Father,” was fed by a need to find his place in the civil rights movement, to prove himself “not alone in my particular struggles.”

Those struggles include uneasiness with being black. When in Kenya, he finally experiences the “freedom that comes from not feeling watched…here the world was black, and so you…could discover all those things that were unique to your life without living a lie or committing betrayal.” His views of the United States and of Europe are tinged by antipathy to white colonialism. During his visit to Kenya he decides the white tourists are “an encroachment”; he resents that they exhibit “a confidence reserved for those born into imperial cultures.” Obama carries baggage.

Rubio grew up listening to his polio-stricken grandfather extol the virtues and values of the United States. Rubio recalls that like so many proud immigrants, the old man impressed upon his grandson that “there was no limit to how far I could go, because I was an American.” While Obama’s upbringing causes him to focus on America’s “darker periods,” Rubio’s relationship with his native land is celebratory. Early in his presidency, Mr. Obama declines to proclaim America’s exceptionalism while Rubio shouts it from the rooftops.

Not to mention Obama being raised by communists.
