Gabrielle Giffords, former US Representative from Arizona - Reportedly inspired by Supreme Court Justice Sandra Day O’Connor to register as a Republican at age 18, Giffords switched to the Democratic Party in 2000 to run for a seat in the Arizona State House. She went on to serve in the Arizona Senate and the US House of Representatives as a Democrat, before surviving a 2011 assassination attempt in Arizona.
Crosshair Symbols - Shortly after the 2011 shooting of Rep. Gabrielle Giffords in Arizona, Representative Bob Brady of Pennsylvania announced that he would introduce a bill making it a federal crime to use "language or symbols that could be perceived as threatening or inciting violence against a Member of Congress or federal official." His intention was to ban crosshair symbols like those on a map used by Sarah Palin to demonstrate which congressional districts she was targeting for the 2012 election season. Brady's idea was to expand Expand Title 18, Section 871 of the US Code (threats against President) to include more public servants from written threats. Conservatives responded by finding several examples of Democrats using similar crosshair symbols on campaign material.
