As the standoff heats up between Donald Trump and the Freedom Caucus - is the Republican Party on the verge of all-out civil war?

And if so - who'll come out on top: Trump and his red hat-wearing army or the Koch brothers and their million dollar mercenaries in Congress?

Donald Trump has now set his 140-character bulls eye on the House Freedom Caucus.

The Freedom Caucus will hurt the entire Republican agenda if they don't get on the team, & fast. We must fight them, & Dems, in 2018!

This morning - he told his 27.2 million Twitter followers that "The Freedom Caucus will hurt the entire Republican agenda if they don't get on the team, & fast."

Trump then twisted in the knife by saying that "We must fight them [i.e the Freedom Caucus] & Dems, in 2018!"

So if Trump goes to war with the Kochs/Freedom Caucus, who wins? Who has more power?
