Cynthia Nixon has Charlotte鈥檚 vote! After her Sex and the City costar announced a long-rumored bid for governor of New York yesterday, Kristin Davis wasted no time in tweeting an enthusiastic endorsement. (So Charlotte of her!)

鈥淚 am so proud of @CynthiaNixon,鈥 Davis tweeted hours after the news broke. 鈥淣o one cares more than she does about EVERY person getting a fair change and a good education. I know she would be an excellent Governor!鈥

Davis, who starred alongside Nixon in SATC for six seasons and two movies, was also quick to put her money where her mouth is, noting that she had become a 鈥淒ay 1 Founding Donor鈥 and encouraging her 273,000-plus Twitter followers to do the same. 鈥淚鈥檓 excited to support someone I have known for 20 years to be one of the most intelligent and caring people in my life,鈥 she wrote.

Willie Garson, who played Carrie Bradshaw鈥檚 close pal Stanford Blatch, also proudly announced that he鈥檚 in Nixon鈥檚 corner. 鈥淚 can鈥檛 think of anyone who鈥檚 more prepared, more caring, more educated on the issues and more READY than @cynthiaenixon,鈥 he posted on Instagram, along with Nixon鈥檚 two-minute announcement video. He later added on Twitter: 鈥淎n educated, concerned, positive candidate, filled with empathy, not out for personal gain, who cares about SERVING, nor has spent life as a CAREER politician? We can pretty much ALL agree on this one鈥︹

Several other celebrities, including Allison Janney, Rosie O鈥橠onnell, and Sophia Bush, voiced their support, too. 鈥淐ynthia is brilliant and her concern for people is boundless,鈥 Bush tweeted. 鈥溾業f not us, then who?鈥 INDEED!鈥

Nixon, who was born and raised in New York City, will face off against incumbent Governor Andrew Cuomo in this year鈥檚 Democratic primary, and she鈥檚 made one message clear: 鈥淚 love New York but something has to change.鈥
