In a state where Democrats are an endangered species, Ruben Gallego is a liberal's dream candidate. He's a Harvard graduate and Iraq War veteran who's fought hard for every progressive cause as a state representative, from marijuana legalization to supporting a recall of Sheriff Joe Arpaio. After just four years as a state representative, Gallego ran to represent the Phoenix area in Congress — and won his primary handily, beating longtime political operative Mary Rose Wilcox in August. His wife, Kate, is no slouch, either — and certainly not a typical politician's wife. She's also a graduate of Harvard (that's where the two met) and won a hotly contested seat on the Phoenix City Council in 2013. They're such dedicated Democrats that Ruben actually proposed to Kate at the 2008 Democratic National Convention. Even in a Republican hotbed, these Gallegos are going to be around a while.
