Kyrsten Sinema is the first woman Arizona has ever elected to the Senate, and the first Democrat the state elected to the chamber in 30 years. She'll make history as the first openly bisexual senator. For now, the win in Arizona means that Democrats have narrowed GOP gains in the Senate to only one seat so far — Republicans defeated incumbents in North Dakota, Indiana and Missouri, but Democrats flipped seats in Nevada and now Arizona. There are two outstanding races, including Florida, where a recount is underway to determine whether Republican Gov. Rick Scott's narrow lead over Democratic Sen. Bill Nelson will hold. Democrats' win in Arizona means they were able to expand their reach into traditionally red territory — something they did in the House last week as they flipped control of the chamber, but have yet to do in the Senate. President Trump won Arizona by 4 points in 2016.
