During the final presidential debate of 2019, one of the moderators posed a question about a topic that rarely gets attention on the debate stage: What steps would candidates take to help disabled people get more integrated into the workforce and their local communities?

For Andrew Yang, the question was both political and personal. His oldest son, Christopher, is on the autism spectrum.

Julián Castro went to Des Moines this week and told Iowans they shouldn't vote first.

"I'm gonna tell the truth.

Former New York City Mayor Michael Bloomberg is making a late entry into the presidential race, a move that could upend the Democratic nominating contest this spring.

Bloomberg said in a statement Sunday that he is running to rebuild America and defeat President Trump, whom he says "represents an existential threat to our country and our values."

South Bend, Ind., Mayor Pete Buttigieg, age 37, is one of the youngest presidential candidates in modern American history and, if elected, would be the youngest president ever.

Buttigieg entered the race this spring focused on the idea of generational change, often telling voters that he fears what the United States will look like in the year 2054, the year that Buttigieg will be the same age as President Trump is today.

A former aide to Barack Obama said that concerns the former president raised about ideological "purity" were aimed at explaining that governing requires having conversations that include people whose values you may not share.

Speaking Tuesday at an Obama Foundation summit in Chicago, Obama said that he worries that some in the Democratic Party's left flank are too worried about ideological "purity" among their fellow Democrats.

Greg Demetri hit the jackpot. When he picked the location for Villa Toscana, his nearly one-year-old Italian restaurant on the main stretch of businesses in Central, S.C., he had no idea that the building had once been owned by the town's most famous resident, Sen. Lindsey Graham.

This post has been updated to note that Graham has now officially gotten into the race for president.
