UNDATED (CBS) -- "CPAC" is the Conservative Political Action Conference. It's a crucial event for Republicans testing the presidential waters.
But this year, one of the most prominent names in the GOP, is not on the list. Chris Christie may be in trouble with the right.
Speaking at this year's event is a who's who of GOP leadership including early favorites for the 2016 Republican presidential nomination.
But one frequently mentioned front runner won't be there. New Jersey Governor Chris Christie, the popular politician known for his quick wit and blunt style has not yet been invited even though he was a featured speaker at last year's event.
In today's political landscape starkly divided along party lines, Christie has angered some conservatives who see him as too cozy with Democrats.
When superstorm Sandy devastated New Jersey's coastline, Christie praised President Obama's quick response only days before the election. He said in October, "I cannot thank the President enough for his personal concern and compassion for our state and for the people of our state. "
In January, Christie blasted the Republican controlled Congress, charging it was GOP leaders who were tying up relief funds.
After the Newtown school shooting, he took on another conservative sacred cow, the NRA. When the gun lobby ran an ad saying, "Are the president's kids more important than yours?" Christie defended President Obama, calling the attack "reprehensible."
And on Sunday night, Christie once again incited his party's conservatives when he was photographed sitting next to first lady Michelle Obama at the Governor's Ball.
Even a 74 percent approval rating may not be enough to get him invited to CPAC's party.
