Aside from National Security being the hottest talking point right now, very little. Perhaps Dems want to argue that back alley doctors would sneak into the country illegally, since women wouldn't have access to the abortion they want through legal means. It's the oy argument I can think of and it is flimsy as hell.
Dems always weaponize sex. Always.
Snowden worked for the CIA for a while. The current theory is that Snowden leaked the NSA spying activities on behalf of the CIA in order to give the NSA a black eye.
You don't have to believe that, but a good question to ask yourself is how in the hell did Snowden leave the country with a head and laptop full of government secrets without any outside help? Would seem next to impossible to me. He hides out in Russia and has a movie made after him? It stinks, we're supposed to champion Snowden as a hero.
