Day two of the 2015 Conservative Political Action Conference began at the same fevered pitch as the opening act Thursday. Presidential hopefuls drew cheers and jeers—and plenty of tweets as well.

Sen. Marco Rubio, R-Fla., was the first 2016 contender to take the stage Friday. Audience reactions were mixed.

Rubio spoke about his social conservatism and passion for life.

He also stressed his outsider status and his future ambitions.

When it came to immigration, Rubio spoke of regrets on his role in the bipartisan.

The slew of presidential contenders continued with former Texas Gov. Rick Perry.

Some people made fun of him.

But Perry had plenty of fans.

During the speech, he demonstrated his support for Israel.

Perry also took a shot at President Obama by yearning for the Jimmy Carter years.

Sen. Rand Paul, R-Ky., drew a large audience for his speech. Supporters swarmed the main ballroom wearing “Stand With Rand” shirts.

This was despite Paul being delayed by a Senate vote.

Paul discussed several topics that have excited libertarian-leaning conservative millennial voters, including curbing the power of Congress.

Things got heated later in the day as former Florida Gov. Jeb Bush took the stage. The room—including the press filing center—was packed, with many people standing in the aisles to watch Sean Hannity interview the likely 2016 contender.

Talk of walkout begin to swirl.

Bush was greeted with a mixed reaction from the crowd.

When pressed by Hannity on his views, Bush’s fans gave him hearty applause.

Some questioned who these fans really were.

Day three looks to be just as fun.
