Via Mediaite explains the defference between himself and Ted Cruz:
President Obama does not see any similarities between himself and Sen. Ted Cruz (R-TX). During an interview with the Associated Press released Saturday morning, Obama rejected the notion that he “set a precedent” for first term senators like Cruz, Rand Paul (R-KY) and Marco Rubio (R-FL) who have sought out the spotlight early in their political careers.
“If you recall, when I came into the Senate my attitude was, I should just keep a pretty low profile in the Senate and just do the work,” Obama told the AP, harkening back to early 2005. He admitted that the media may not have let him keep that low profile, but added, “I didn’t go around courting the media, and I certainly didn’t go around trying to shut down the government.”
“And so I recognize that in today’s media age, being controversial, taking controversial positions, rallying the most extreme parts of your base–whether it’s left or right–is a lot of times the fastest way to get attention or raise money, but it’s not good for government,” Obama continued. “It’s not good for the people we’re supposed to be serving.”
Unlike the brash Ted Cruz, Barack Obama gave his first nationally televised speech before he reached the Senate. At this point in his sole Senate term, Obama was (supposedly) writing his second memoir. In March 2007 (after just slightly more than two years in office) Obama announced he was running for President.
