This is a recent article explaining why American Christians should not vote for Mike Huckabee. Let me just summarise the reasons:
* He supports the "validation of elites", whatever that means.
* While the head of the Arkansas Baptist convention, Huckabee did not "appoint" conservatives to certain positions, which depends upon what "appoint" and "conservative" means.
* As Governor of Arkansas, Huckabee "didn't surround himself with conservatives" and instead "kept many agency heads appointed by Clinton".
* He is very supportive of increasing Mexican immigrants to America.
* He "embrace(s) the notion that fidelity to the Gospel requires privileging the interests of non-citizens over those of fellow citizens (ie immigrants)".
* He supports a federal law to ban smoking in the workplace.
* While Governor of Arkansas, state tax revenue increased by 65.3%.
* He increased taxes.
* The Cato Institute, a libertarian "think tank", gave him an "F".
* He refused to sign some no tax pledge by Grover Norquist.
* In summary, he is not a conservative, not a constitutionalist, but rather an opportunistic traitor to his country.
Now I don't know much about the guy, but there is nothing in this list of grievances that is remotely Christian. Christians are free to decide for themselves whether it is better for governments to be bigger or smaller, or whether taxes should be increased or decreased, or whether they think the US Constitution is fine as it is or requires more amendments to improve it. The reason for this is simple - the Bible gives very little information as to how political entities conduct themselves in the new Covenant era. Christians should vote for the party they think will best help the country, rather than sticking with one particular ideology or single issue.
Christians on the right cannot claim that right-wing, conservative policy is somehow Christian in character. It is not. That doesn't mean it is wrong, it just means that it is not divinely directed. For me on the left, I obviously think that many leftist policies and practices result in better and more efficient outcomes than currently practiced by the right - but I don't somehow think that these leftist policies are based on scripture.
In short, I'm arguing that Christians should consider voting left not because it is biblical (which it isn't), but because it offers a better chance of enriching society (in a non-utopian way). Christians on the right should have the same attitude, rather than arguing that the right-wing is somehow biblical.
