It's a day for Democrats to celebrate as Barack Obama begins his second term as president. But for Republicans, it's a different story.
It's a day for Republicans to contemplate why Mitt Romney wasn't taking the oath today. The GOP party went into the election with high hopes, but lost decisively.
On this inauguration day, Republicans once again find themselves the loyal opposition with Democrat Barack Obama in the White House.
Arizona Republican Party Chairman Tom Morrissey says it's not what they wanted.
"It is not a happy day for Republicans, but it is a hopeful day. We counterbalance each other, the Democrats and the Republicans and that is the way the country works sometimes, we win sometimes we lose," says Tom Morrissey, Arizona Republican Party Chairman.
The head of Arizona Republicans says it's a day for Americans to pull together and celebrate democracy. But it doesn't mean they have to agree with the administration.
Morrissey believes the president has "socialistic tendencies."
"I feel that Barack Obama is on the wrong side of the issues, not a bad guy just on the wrong side of the issues."
As President Obama begins four more years in the White House, it's a chance for Republicans to think about what the GOP needs to do to get back in power.
"Going forward I believe the party has to change and understand it has to be more welcoming."
That means, especially, attracting more Latino workers.
The head of the Arizona Republican Party thinks a more welcoming tone is key -- but he said he opposes the Dream Act, which Latino voters overwhelmingly support.
Republicans will have to figure out how to reach out without losing support from their core supporters, who tend to be older and white.
