But when were Democrats so anti-war? Plenty of them voted for the Iraq War Resolution (though more voted against it than for it in the House I believe) and pretty much everyone voted to strike Afghanistan. I remember Barbara Lee came out against that, anyone else? I like to separate out Democrats, liberals, and leftists. If we look to elected politicians of any party to set our moral guidelines we would be in a very dark place.
I personally IRL do not know any anti-war people who became pro-war once Obama was elected. However, there is no doubt that many middle of the road Democrats on the internet are pro war now. I just don't know how representative they are.
