Get this: A ridiculous scene in the upcoming Avengers film had Captain America lamenting the loss of “loss of health care and welfare” in his country. Thankfully, it was cut from the final product by director Joss Whedon:
One of the best scenes that I wrote was the beautiful and poignant scene between Steve and Peggy [Carter] that takes place in the present. And I was the one who was like, ‘Guys, we need to lose this.’ It was killing the rhythm of the thing. And we did have a lot of Cap, because he really was the in for me. I really do feel a sense of loss about what’s happening in our culture, loss of the idea of community, loss of health care and welfare and all sorts of things. I was spending a lot of time having him say it, and then I cut that.
Aside from the ridiculous historical inaccuracy of such a statement (healthcare and welfare coverage have both increased dramatically since the 1940s, for heaven's sake), it's simply something that Cap would never say -- unless he's in the hands of a typical leftist contemporary comics creator. Some commenters at the article link say that Whedon is more a libertarian (he created "Firefly"), but Avi Green at FCMM believes the liberal slant given Whedon's abortion arc in Buffy the Vampire Slayer comics.
Nevertheless, Cap, over his long history, has been quite reluctant to get into political debates. In my view, Cap's philosophy is best exemplfied by the following panel from Daredevil #233, the "Born Again" storyline written by Frank Miller:
