I'm not an evangelical, but I'm just curious what you might be talking about.
When liberals criticize believers for not following Jesus, it is usually because liberals think Jesus was preaching about the use of government power, when really he was preaching about how to convert an individual's soul through, among other things, personal charity. Personal charity (and helping the poor) is the tool, not the goal.
He wasn't saying what governments should do with the power they have. He wasn't saying what individuals should do with other people's wealth. He was saying what individuals should do with their own wealth...again, as a means to an end.
If he was interested in feeding the poor, he would have spent more time discussing government social justice policy. But, his only comment on that was to acquiesce to government, not use it actively: "give unto Caesar what is Caesar's."
Instead, he was interested in using the act of private charity for the poor (among other tools) to convert the souls of both the giver and the receiver of the charity.
Using government force to take money from one group of people and give it another group of people is not an act of charity which converts (i) the soul of the voter (because they are actually taking from others), (ii) the soul of the receiver (because they are entitled to the entitlement), nor (iii) the soul of the person actually providing the wealth (since the wealth is being taken from them as a legal obligation, at the point of a gun by the government).
