Even on the Left, there are gradations of bad. Markey is one of the worst. He actually ran ads in the primary proclaiming that he would keep late-term abortions available.
Do some research. I don't know anything about Gomez except that, at some point in his life, he was motivated to serve his country. That puts him miles and miles ahead of the disgusting Markey.
This is the people’s republic of Massachusetts. They are not going to elect a conservative under any circumstances. You gladly take a guy like Gomez just to get his vote to organize the Senate for the R’s. It’s a no brainer.
