John McCain is the epitome of establishment Republicans who spend more energy defeating conservatives than they do Democrats.

And during Donald Trump’s presidency, he has stayed true to form.

But he’s gone beyond just being a critic to performing a disgusting act of betrayal.

Donald Trump released his fiscal year 2018 budget request.

Trump is acting on long held Republican principals of slashing spending and shrinking government.

His budget eliminates 66 programs and slashes trillions in spending.

Establishment Republicans – who will campaign on limited government, but then vote to allow the big government gravy train to chug along – recoiled in horror.

One of the loudest critics was John McCain.

The failed 2008 Republican nominee declared the budget “dead on arrival.”

Breitbart reports:

“Tuesday Sen. John McCain (R-AZ) said President Donald Trump’s budget was dead on arrival.

In a statement, McCain said, “President Trump’s $603 billion defense budget request is inadequate to the challenges we face, illegal under current law, and part of an overall budget proposal that is dead on arrival in Congress.”

McCain was asked by MSNBC’s Kasie Hunt, “Can I ask you about president’s budget? Is it dead on arrival?”

He replied, “Yes. and the commitment to rebuilding the military cannot be fulfilled with this level of spending. It is $30 billion too short.”

Instead of working with Trump to drain the swamp, McCain is fighting to protect its creatures.

Barack Obama nearly added as much debt as the previous 43 Presidents combined.

Trump entered office facing an ocean of red ink.

So he took action to reverse the tide.

His budget – which balances in ten years – is a good first step.

It guts domestic welfare programs and implements real entitlement reform.

And it includes $1.6 billion for the construction of the border wall.

But to big government Republicans like John McCain, defending the swamp – and every dime of funding it can suck in – is the top priority.

Republicans are facing political headwinds in 2018.

The party in power almost always suffers losses in the midterm elections.

If the GOP fails to act on Trump’s agenda, the party faces certain doom.

A wave election would mean Nancy Pelosi becomes Speaker of the House and Democrats immediately move to impeach Trump.

But if the GOP sticks to their guns and works to pass Trump’s budget, they will fulfill the promises made to the voters who elected them.

That is the only way to maintain the enthusiasm that will spur Republican voters to turn out – and minimize any chance of Pelosi once again clutching the Speaker’s gavel.
