(CNN) It's just one election, but the first congressional special of 2019 suggests a better national environment for Republicans than the one they faced in 2017 and 2018. Republican Fred Keller easily defeated Democrat Marc Friedenberg by 68% to 32% in Tuesday's Pennsylvania 12th special congressional election . If nothing else, the special election results do indicate that Democrats may not have a huge enthusiasm edge on Republicans. The good news for Democrats is that it's very early in the cycle with many more special elections to come and special elections are just one indicator of the political environment. Still, Republicans can point to special elections as a potential sign of improvement heading into 2020.
