"Despite the frequent drama at the political level, America and Americans have found a comfortable center line in what it is they want their government to do and what it is they accept their government doing."
I do not understand the usage of 'it is' after 'what in' the sentence above.
Were they used for emphasis only? Can I omit them altogether?
Between what? They are not balancing what they "want" the gov't to do with what they "accept" it doing.
Well, the sentence seems to say that that's what they have found the centre line between. They may want the government to do nothing about health care but accept its providing limited healthcare. Or, they may want it to provide a cradle-to-grave welfare system but accept a limited system. Only more context can tell us exactly what the cenre line is between.
