When firebrand Republican senator Ted Cruz went on conservative Laura Ingraham's radio show last week, the topic of conversation swiftly turned to Barack Obama.
As the President prepares to be inaugurated tomorrow for a second term, Cruz, who is a Tea Party favourite freshly elected from Texas, let loose with both barrels: "He is feeling right now high on his own power!" he fumed.
Cruz was particularly angry about Obama's plan to enforce tighter gun controls. But the President appears to be preparing a whole series of reforms that will raise the ire of the right.
He has vowed action on immigration, hinted that he will try to tackle climate change, and has already taken a much tougher line with Republicans on fiscal issues, forcing them to agree to a tax rise for the wealthy.
For many, it seems Obama has been reinvigorated by his victory.
